Dave found and shared these photos of a Dualmatic hub box with an information sheet inside it.

Early Allstate Hubs $150
Maury shared these hubs for sale. They are Allstate hubs and, likely, a very early set. My guess is the these were likely built by Husky/Dualmatic, but I am not familiar enough with hub innards to say for sure. I can’t quite find a brand-name hub with the cover that looks quite like this.

“These hubs are all complete and turn freely. The dial is heavy case aluminum. These only work with threaded axles ends. I tried putting them on the later snap ring style axle and the snap groove does not protrude out. Outer case was chrome originally. They seem like a really well built early twist lock hub. Asking $150 obo plus shipping. I also have a picture of how the innards went when I took them off the axle.”
Watson Hub Variant or Modified?
This hub appeared in a Facebook photo posted by Josh. It appears to be a Watson hub (may have been private labeled through Sears), but part of its case was either 1) cast differently or 2) modified. Given The Jeep has spent its life in California, it’s likely some form of the Watson hub, but I’ve not seen one quite like this.
Allstate Hubs of CJ-2A Lebanon, OR $65
They look like a good price for a vintage set of Husky produced and Allstate branded hubs.

“Surplus to my needs are a set of 2 matching Allstate locking hubs that came off of a 1947 Willys jeep flat fender. I do not know much about them other than the brand shown on them. They appear to need some cleaning, but I assume they work as they are supposed to. You be the judge of that.”
The Free-Lock Corporation and Their Hubs
UPDATE VII: A set of NOS Free-Lock hubs included documentation stating that by December of 1973 Free-Lock had become a “Quality Division” of Dualmatic Products Company. So, I believe this suggests that Free-Lock was acquired by Dualmatic, so now the questions are 1) when did this happen and 2) why didn’t Dualmatic use the branding sooner than circa 1970 (there was a gap between the end of Free-Lock in 1959 and the re-emergence of the brand circa late 1960s or early 1970s).
UPDATE VI: I located a set of Free-Lock hub instructions that are a pre-view for a later set of near identical Dualmatic instructions. This is clear documentary evidence that Dualmatic was linked to Free-Lock.
UPDATE V: I recently packed many of my father’s tools to bring them back to Prosser. I was a regular user of them when working on my bicycles, then my jeeps. So, I thought I knew them pretty well. That is why I was so surprised and did a double take when I removed this tool from a drawer and read the name stamped on it: FREE-LOCK WRENCH …
What??? Where’d that come from? I once asked Dad about Free-Lock hubs, but he didn’t know anything about them. So, I don’t know how he obtained it.
Anyway, given the primitive nature of it, I’d have to guess it was a first generation version of the wrench. As seen below, a second, more elegant curved-design with a better branding stamp was likely introduced after this version.
Here’s a reminder of the other version of the Free Lock Wrench:
===================
UPDATE IV (From February 12, 2017): This page contains two later model Free-Lock hubs that resemble Selectro hubs. My theory is that Free-Lock might have evolved into the Selectro Company: http://www.ewillys.com/2019/07/08/selectro-husky-dualmatic-overview/
UPDATE III: Thanks to Steve, we’ve discovered an additional version. It is now number 5, which seems to be an evolutionary step between 4 & 6.
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.
Thor Products & White Automotive (Whitco)
UPDATE II: Dinesh obtained these Thor-Automatic looking hubs, but on the cover they read Allstate Power Matic rather than Thor. I suspect they are Thor hubs rebranded for Allstate. Here are some pics:
Here is a the interior portion of a set of Thor hubs:
=========================
UPDATE (May 24, 2021): The October 1963 issue of Four Wheeler Magazine include this Thor-designed product to make shifting the transfercase more convenient. It moves the shifter from the passenger-side of the transmission to the driver’s side. I imagine there are few, if any, of these shifters out there.

More information on some of these companies can be found here: http://www.ewillys.com/2019/07/08/selectro-husky-dualmatic-overview/
White Manufacturing Co. (also known as White Automotive and Whitco over time) was started in the late 1950s by Richard T, Bingman and partners. The company progressed at a modest level making, among other things, aluminum floral display stands. Eventually, White allied with Kaiser and began making tops. White filed for incorporation in 1959. One of the company’s earliest products was a white soft top for jeeps.
The next year, in 1960, Richard T. Bingham filed a patent for a pair of locking hubs. One set would automatically shift into gear when it sensed the axles were being powered (i.e., when the transfercase was shifted into four wheel drive). The second set of hubs added a dash-mounted button to allow for control of the hubs from the driver’s seat (assuming I have interpreted the patent correctly!).
The interesting thing is that Bingham never assigned the patents to the White Automotive Company. Instead, the patents and hubs ended up being used by Thor Products, which also operated out of Colorado Springs (though sometimes the address is Manitou Springs, a small town just west of Colorado Springs).
This suggests that Bingham had some time of relationship with Thor, but his exact connection to Thor isn’t known at this time (my guess is that it was a subsidiary or sister company of White).

Unusual Clutched Hub; Possible Prototype?
Brian posted these pics of a hub he has to FB’s Flatfendering Aficionado Monthly group. It’s not something I recognize. The work looks good enough to have been a prototype hub that never made production. It may have been an auto-engaging hub? Some commenters suggested a type of limited slip hub, where when a wheel begins to slip it auto-engages.
Brian wrote, “Has anyone ever seen these locking hub contraptions? Were these produced or is it a one-off? It appears to use 3 clutch plates and the ring in the center moves down over the roller cams to apply pressure to the plates. The covers look to be welding bottle caps that have 2 access holes to pry the collar from the outside.”
Unusual Summer Hubs Redlands, CA $40
These are an unusual set of Summer Hubs. I suspect they were custom made.

1962 Article on a CJ-5 Build
This May 1962 article in Four Wheeler magazine highlighted a few things. First, it’s a really clean build. I wish the pics were in color, as it’s deserving of some great photos.
Second, if I understand correctly, the rear bumper is actually a gas tank. I’m not sure I like that plan so much.
Third, given this jeep is near Colorado Springs, it probably has the Thor Electro-matic hubs, which allow a push button engaging of the front hubs. And, because they are short hubs, the front wheel covers can be placed over them.
Fourth, this has an early vacuum brake assist. Herm carries a newer version of this.
Fifth, the White top on this jeep is beautifully styled in my opinion.
