Hi Don,
This may be a brother to the #4 All Steel that you have, at first I thought it might have been the same trap, not knowing if you still had yours, but after looking at the two closer, they are two different traps. When you consider they are both close to 125 years old, they have been well taken care of through the years, which is remarkable, considering they were trapping traps before the became collector traps. The one I have came off eBay a few years back.
By the way, nice trap Don, thanks for showing it.
