Barney sent me a Warn Locking Hub brochure which turns out to be a match for a similar Warn Lockomatic Hub brochure I already had. These are rather small (about 4″ in diameter), so I’m surprised either one survived as well as they have.

One thing that’s evident from these brochures is that the Lockmatic hubs lacked the rings (or perhaps indents or groves are better terms) on the lower portion of the hub that the Locking Hubs had.

Here are the opened brochures:
