Could someone give me the approximate date Oneida Victor stopped using a square rivet on the cross piece and a figure 8 chain.
Thanks

I would guess sometime in the 1930s?

I'll expand on this a bit.. Ribbed Jaws... Square Rivet...Figure 8 Chain

This is something that I copied off of here a while back and don't remember whom to give credit:

The original Victor traps were called "The Victor" and were made from 1886 thru around 1889 by Oneida Community. They had cast jaws with bolted jaw posts like a Newhouse or Hawley & Norton. They were also made in a dog less model. Around 1889 the Oneida Community dropped the "The" and called them "Victor" traps. Oneida Community continued to use cast jaws on Victor traps until around 1918 when they started to make the jaws from pressed steel for the smaller sizes #0 thru #2. In 1920 they went to what they called the "ribbed" jaw on the same smaller size #0 thru #2 traps. Oneida Community continued to use cast jaws on the #3 and #4 size Victor traps until Feb. 1925 when they sold the trap business to what would be called Animal Trap Comp. of America. Animal Trap Comp. used steel jaws on all of their Victor trap except the #3N and #4N.

Thank You
