Bill shared these.

1. Willys Summer Hubs, early waffle version. **SOLD** 
   “These are very old Warn hub covers. Mostly they are antiques or novelties now I think. They would be used if one wanted to tow their jeep or operate it in 2WD for extended periods of time without pushing all the front axle, drivelive, ect. They are designed to let the front wheels turn freely without allowing grease out or dirt in. Very nicely made with Torrington bearings. I’ve never seen these before, maybe another Jeep nut has and knows more than I do about them.”
   
2. Dualmatic Hubs **SOLD** Was $100.
   “WILLYS JEEP HUBS to fit on DANA 25 front axle with 10 spline shaft. These Do not require the axle nut be cut off like some of the new hubs do. There are 4 hubs here, 3 are made by Dualmatic and the 4th is of a kind I have not seen before, it just says “Denver”.”
   

These are the later “dimple” model of hubs.
