A December 1944 article in Popular Science highlights tandem towing:
UPDATE II: Thanks to Frank Day and his grandfather Merton, who saved this rare piece, here is a scan of an eight page brochure related to the Free-Lock corporation. I also uncovered the possibility that the Free-Lock Corp was the forerunner of the Cutlas Tool & Mfg. Company, which also made hubs. Cutlas emerged about the time Free-Lock disappeared and the companies have at least one, possibly three execs in common (I want to gather more info on this before confirming).
This November 1942 article from Popular Mechanics titled “Miracle on Wheels” featured the jeep and shared some of the success stories from its use internationally. You can read the entire issue on Google or purchase a cheap copy off of eBay
Speaking of Hydraulic Lifts, the Love Tractor Company (or perhaps more accurately Love Industries — I’m not clear on the difference) made a lift and also sold a willys-engine powered tractor.
According to the Standard Catalog of Farm Tractors 1890-1980, by C.H. Wendel, Love Tractor offered model J51 that was built around a Willys CJ-2A engine. This may have been a repurposed Empire Tractor, because at least one source suggests Love purchased eighteen Empire Tractors when Empire dissolved. Anyone know more about the ‘Willys’ Love Tractor?
The February 1947 issue of Popular Science has an article on the Love Hydraulic Lift System distributed by Newgren.
There is also an article about the Love system and Newgren in a 1949 issue of Farm implement news – Volume 70 – Page 56.
David Silberman pointed out the ‘Leaping Lena’ article from the October 1941 issue of Popular Science (I thought I’d purchased this issue to scan, but apparently I didn’t do that). It’s an interesting review of the prototype jeeps. You also can view the entire issue on Google.
An article about the Odograph was published in the December, 1944, issue of Popular Science. At 200 pounds, the Odograph auto-created maps as soldiers navigated towards some objective. I couldn’t locate any records that indicate how many were made (anyone know), but there it appears there are nine jeeps that still have them (based on the latest info I could find). I found a few different references about it over at G503.

The December 1949 issue of Popular Science highlighted this unique attachment for the jeep. You can view this article on Google books.
The July 1956 Popular Science article doesn’t indicate which country ordered this special search light, but this mobile, self-contained spotlight put out some serious light.
Popular Science published a January 1943 article with a variety of GPA / SEEP pictures, including a nice breakdown of the dashboard (handy for my description of a seep dashboard in my upcoming book).
Here’s an interesting article in the May 1945 issue of Popular Science about welding on the battlefield that includes several references to using jeeps as portable welding units. There is a copy on eBay for only $5.99. Here are a couple images from the article:
The Last Chancer, a wooden train built on a jeep platform, is documented at the Helena History Museum. You can view additional pictures at the Museum page. A Last Chance Train still exists, but has been upgraded.
In this early picture taken in 1954 you can see what appears to be a CJ-3B peering out from it’s enclosure.
Here is the Train as of 1957.
The Last Chancer made an appearance in the 1956 issue of Popular Science on page 104:
The September 1947 issue of Popular Science has this cool picture of a truck powering a saw.
