UPDATE: **SOLD** Was $5500.
This has a CJ-5 grille, but an M-38A1 body. The rear has been extended on the body. This might have a set of Thor Auto-matic hubs on it, but I can’t tell for certain.
“V-6, 227 Conversion, hard top and hard doors included, and tow bar”
John recently rebuilt a set of Cutlas Selective Hubs, the type with the knob that rotates to engage and disengage the hub. There appear to be at least two styles of these hubs, one with a flat top and one with a groove, so that a tool (or improvised tool) can be used to help engage, disengage the hub.
This exploded overview from 1961 shows how the parts assemble (see the full brochure below this post):
As you can kind of see from this diagram, there are two sections: 1) is the hub cap that holds the knob and the spring in place (from part 107-2 in the middle and everything to the right of it) and 2) the hub base (part 108-2 and everything to the left of it).
John wrote, “Overall I’d say these are my favorite hubs I’ve worked on so far. I have a pair of Warn hubs (with the tiny needle bearings) and a pair of Selectro hubs (big chrome knob type). The Warns seemed like a real pain to rebuild since the needle bearing were in rough shape. And the Selectro hubs, while very easy to operate, were probably the weakest design I’ve seen.”
Here’s a look at John’s finished product, as it’s the best example a complete hub next to a hub with the top separated from the base:
HUB CAP:
We’ll start with the hub’s cap first. John provided the following note: “To remove the coupling piece (part 102-2 Coupling) from the chrome cap (with the cutlas knob) you have to line it up right with the correct groove, then push down firmly against the spring inside (part 110-2 coupling spring). While pushing down spin the coupling, and then the coupling spring will pop the coupling right out and its free.”
With the inner portion of the cap apart, you can see the coupling ring, the coupling, the coupling cam spring (part 107-2) and the coupling cam pins (parts 105-2).
This December 1961 back-to-back brochure shows the parts break-downs and price lists for the early non-slot Cutlas Selective Hub model 100-2 and the Power Lock Hub. See John’s rebuild of the Cutlas Selective Hub here.
UPDATE II: This version of the Power-Lock brochure was posted to eWillys in May of 2023.
I hadn’t seen this version of the Cutlas Power-Lock brochure. Given the 1959 date, this is likely one of the earliest Power-Lock brochures. This brochure doesn’t not include a form number.
======================
UPDATE April 16, 2020: The bottom brochure examples show a brochure from 1958, probably Cutlas’ first one. You’ll note that the brochure (and the hub itself) was branded “Power-Lock”. However, the 1960 brochure (shown just below this text) lacks any “Power-Lock”branding. Perhaps someone else knows why, but I can find no reason why. Maybe there was some concern about whether the patent would be awarded? (It wasn’t awarded until 1962).
1960 Cutlas Hub Brochure:

This Power-Lock was the first hub patented (1958), copyrighted (1958), and sold under the Cutlas brand. As I mention in my Free-Lock article, for reasons unknown, the president of Free-Lock became the president of Cutlas. Even more curious, the last two model of Free-Lock hubs were WL-57 and WL-58.
And, what was the Initial model of the first Cutlas hub you ask? That would be WL-6, shown below (1958 Cutlas Hub Brochure):
More on Dualmatic/Selectro hubs here.
As part of a discussion on hubs on Facebook, someone from Australia posted a photo of his CJ-6 that came with these unusual hubs. They are similar in external design to the Dualmatic/Selectro, have only 3 “bumps” or “tabs” rather than the standard six around the side of the hub. There’s no brand name on the hub or any other identifying characteristics. A search on Australian 4WD sites and on the Australian patent site did not reveal any information.
Anyone ever seen these?
For comparison, this is a Sears private branded Dualmatic/Selectro (sears branded) hub in the first pic and a Free-lock branded hub in the second pic.
This includes a working set of Thor Electronic Hubs (and the first pic I’ve seen of the switch to engage the hubs). These are the “Lectro-Matic” version of the hubs (there was also an automatic version). Dan documented a set of the “Lectro-Matric” hubs here.

Ca title & current registration in my name”
UPDATE: This post has been updated with more pics. Also, there is currently a Kelly Hub brochure on eBay.
In May of 1957, DA Ruben L. Beck filed a patent for a new hub design. Beck was a dreamer and like many dreamers, some saw him a genius while others thought him just plain crazy. Beck’s goal was to create a simple, but effective, four-wheel-drive hub.
Beck had already made an early impact in the jeep world, when he founded D.L. Beck Manfucaturing in Middleport, Ohio, a company that made hardtops (see Beck hardtop history here).
Beck sold his hardtop company to Hubert A. Kelly, in the 1950s but Beck and Kelly remained in contact. The date of the sale, thought once to be 1951, is less clear after this document hit eBay in 2014. It indicates Beck was still selling hardtops in 1954.
No matter when the sale occurred, Hubert took control. It wasn’t long after the patent filing that Mike Kelly, Hubert Kelly’s descendent, remembered seeing the hubs for the first time. He thought that was about 1958. I asked that he review the patent and Mike sent me the following notes:
“The Kelly Self Locking Hub I knew a was little different than the one pictured in the patent drawing. The housing was larger in diameter and had reliefs milled along the outside to allow clearance for the mounting bolts. The internal parts looked very similar to what I remember. I’m pretty sure the final Kelly product was a Beck design. I don’t recall anyone else working on it.
The hubs were manufactured in Charleston West Virginia. We already had an large machine shop there on Broad St. So moving production from Ohio to West Virgina was only logical. I know the assembling the hubs could be “interesting” if you weren’t watching what you were doing. Putting the internal workings together with the ball bearings being under spring pressure woke up more than one man who wasn’t paying attention.”
This early Warn manual No. WD-255 sold on eBay for $36.20. My last bid was $35.20, so someone out there outbid me.
There’s a very nice set of Kelly 10-spline hubs for sale over at the Old Willys Forum.
https://www.oldwillysforum.com/forum/index.php?threads/kelly-10-spline-locking-hubs.16970/
“Nice pair of vintage Kelly hubs . Very unique!
These are 10 spline Hubs are smooth to turn and in very nice condition.”
UPDATE: **SOLD** Was $100.
These 10-spline hubs were called the Cutlas Selective Drive Hubs. Some has the indent through the middle like this set, others did not.
“For sale is a set of vintage Cutlas 10 spline locking hubs for Willys Jeeps. These were removed from a 1951 M38 with 20,000 original miles. The hubs were added after its Military duty so they are very low mile and in fantastic condition inside and out. Photos were taken as they came off the M38, clean as can be inside. Only reason im parting with them is because I returned the hubs to Milspec/factory configuration.
Should fit DANA 25/27 Willys MB/GPW, CJ2A, CJ3A, M38, CJ3B as well as some Willys wagons.”
These appear in good shape. You can learn more about the Selectro history here.

I’m way behind on my document scans. I thought I’d catch up today, but between our search for a new bed (Ann’s back is giving her issues) and the fact that Ann accidentally left the plastic bbq brush (why???) in the bbq, which melted into an ugly mess when I turned on the bbq, forcing me to clean the whole thing, all meant that I didn’t have time once again for scans.
Anyhow, here’s the promised Dualmatic brochure. The brochure is directly and has some stains, so they aren’t the best scans. But, they’ll do for now.
UPDATE: **SOLD** Was $2777.
This early M-38A1 has some rare Dana HubLok hubs. It also has a Warn/Saturn overdrive and a Meyer hardtop.

Maury spotted these early Cutlas hubs on eBay. The seller owns “New Jersey’s largest Jeep parts depot”.
UPDATE **SOLD** Was on eBay.
Starting bid is $300.
“Up for auction is a pair of NOS Dualmatic locking hubs. They are Chrome and in excellent condition. Comes with instructions and original decal, bolts, and locking clips.

I won this rare Dualmatic brochure on eBay. I’ll follow up with more detailed pics once I receive the document.
Blaine found a set of NOS Perfect Circle hubs, which look to be private-labeled versions of the Selectro hub manufactured by Dualmatic. Unfamilar with Perfect Circle, I wondered why the company would private label a set of hubs.
It turns out that Perfect Circle had been a leader in the development of piston rings for several decades. In 1963, the company was purchased by the Dana Corporation. It’s possible that relationship led to the private labeling of the hubs. (Read the whole Perfect Circle history here)
These particular hubs should fit the Dana 27 axles, as that was the standard axle on early Scouts (but I’m not expert on the Scouts).
We’ve seen the above hubs branded under multiple names, including Dualmatic, Selectro, Perfect Circle, Free-Lock, and others. But, where did the hubs originate?
Unfortunately, as this point I only have theories rather than actual answers. One theory is that they were developed by Free-Lock, but not patented, prior to Free-Lock’s demise. Somehow, Dualamatic/Husky ended up with the hubs (probably purchased Free-Lock’s assets) and then Dualmatic manufacturing them under the Free-Lock brand, then other brands.
My second theory is that the hub is based on this hub patent from Clark Peterson in 1955.
It has the spring system and It appears the entire top of the hub twists. But, there are some differences. The central bolt does not exist to hold the hub in place, instead side bolds secure the top. Maybe someone who has a set of these hubs can compare it to the hub design above? Below is a schematic of a Dualmatic hub for comparison.
UPDATE: **SOLD** Was $150.
Original box, too!

UPDATE V: This post has a comparison of Husky hub backsides.
UPDATE IV: With this ad August 1973 ad in Four Wheeler Magazine, Husky seemed to want to make it clear that Selectro hubs were Husky products, even though some Selectro stuff had been marked with Dualmatic references over the years.
This is the first full page ad for hubs that I had seen in years from Husky or Dualmatic. Perhaps they were struggling with a branding issue (seems likely to me), so this was the company’s answer.
==================
UPDATE III: You can find a closer look at the Dualmatic hub-with-levers variations on this post.
UPDATE II: Here’s an example of a more standard Selectro-style hub with the Free-Lock branding. It’s the first example I’ve been able to document. It looks more like the heavy duty kind of Selectro.

ORIGINALLY PUBLISHED JULY 8, 2019: Once again, this is more a working post than a polished one. And, it’s a long one. It kept growing and growing as I learned more (and became more confused).Of course, I am left with more answers than questions.
Essentially, I’m trying to figure out when Selectro hubs popped onto the 4WD scene, who controlled them, and how they evolved. That led to looking at Husky, Dualmatic, Watson and FreeLock hubs. I don’t have all the answers just yet … here we go …
TIMELINE & DiSCUSSION:
1959/1960?: The Husky Company launches it’s line of Husky Hubs out of Aurora, Colorado. This hub one of two pieces of evidence of the Husky Company’s existence in Aurora; it has the Husky Company name and location on it:
A second piece of evidence was uncovered on a document found by Maury; the Husky Company was located originally in Aurora, Colorado.
Based on the information on the hub, the Husky company already had a patent awarded (not just filed, but awarded). So, which patent was that? My best guess at the moment is that this 1958 patent awarded to Clark Peterson has the most elements in common with the Husky Hub.
Given there were a couple intervening years between the patent (awarded in 1958) and Husky Hub (unclear when it was brought to market, but I’m guessing 1959/1960), it seems possible that the company altered the design before manufacturing it, which could explain the differences between the patent and the finished hub. The biggest reason I think the two are related is that both the patent and the Husky Hub have a narrow bolt down the center, a unique design not seen in another other hubs.
1961: In 1961 a new name was associated with the Husky Hub: Trade Winds, Inc, out of Boulder, Colorado. My best guess is that the Husky Hub company lacked capital, so it turned to Trade Winds (perhaps which bought a controlling stake in the Husky Company?) to re-introduce the Husky Hubs.
