Victor pans

On or about what year did Victor switch from the rivet pan to spot welded pan?

Teens, 20s Im thinking.....

I believe 1938 was the first year that Animal Trap Company first welded trap pans. I think it was only on the new coil spring traps at that time. They had the new #22 coil spring and the inside double jaw was welded in. Victor long springs pans were welded within a few years.

Thank you, Snakecollector!
