I know John Primble had 3 of the Old Timer stockman patterns that wore John Primble tang stamps.
I know Sears had a similar knife made by Schrade with the Old Crafty shield. Sears also had a large number of Schrade Old Timer patterns made that looked like Old Timers but did not wear the Old Timer name.
I also have several examples of the True Value Hardware Master Mechanic MM Old Timers. I will have to find more pictures, but here are some of the MM89.
Recently I found an Old Timer that was new to me, the TW Old Timer for Trust Worthy Hardware. This is a Trust Worthy sign posted in another topic a few years ago.
I am sure there are other variants of Old Timer patterns that were made as SFOs for many other companies. I am especially interested if they have the Old Timer name on the shield or an OT tang stamp number or if they are an obvious copy of an Old Timer made by Schrade for another company.
Show ‘em if ya’ got ‘em!
