UPDATE II: There’s a newer, updated Dualmatic hub post with comments about the Watson hub here.
These hubs were created about the same time as the dual lever Dualmatic hubs. Moreover, we can state for sure now that there was a specific relationship between the Watson hub and the Dualmatic company.
How do we know this? Because both hubs share the same patent number 2854111:
You’ll note that the patent number 2854111 is the same in both the above items, with both connected to this single lever design: https://patents.google.com/patent/US2854111.
UPDATE: A 1967 Sears Jeep Parts Catalog had a set of hubs for sale that look suspiciously like the Watson hubs. One thing we’ve noticed is that some Watson hubs have “WATSON” imprinted on the hub, while other identical hubs don’t.
So, were these WATSON hubs that were private labeled, or had Dualmatic been making WATSON hubs all along, but now offered them for private labeling? It’s easy to think that Dualmatic might want to separate their Dualmatic branded hubs from private labeled ones. Changing the private-labeled version to this look would help that.
===============================
Original Post: October 30, 2017:
Alaska Paul discovered this Watson Hub article in the 1958 issue of Science and Mechanics magazine. This suggests that the Watson hub was developed in 1956 or 1957, making the company a very early hub manufacturer.
The mechanism looks similar to the early Dualmatic hubs. In fact, the first Dualmatic hub patent filing was in 1956, for a single lever model. Whether that inspired the dual lever model by the California-based H. S. Watson company remains unclear. I have no evidence to suggest Watson ever patented its hub nor how long they sold their hub.
