What is the difference? I am not sure I have ever seen a classic?

Thanks. All of mine are the Super X.

In the US, belisle's are about to get silly expensive.

I just looked on F&T and Bs are only $1.50 more than Dukes. I thought the difference was a lot more.
Unless it’s older stock that’s been in the US before this quagmire began?

Back before Duke copied the Belisle there was a substantial price difference between the 2 traps and a guy needed to make a decision.
Now with the duke super mag, the price difference between the 2 is negligible and the Belisle is an easy decision.

Agree 100%. It was an easy decision even before, for me. I sold my entire collection of mis-matched traps of all sizes about 15 years ago and replaced all with Belisle traps, (body grips, of course). And after experimenting with various brands of footholds, I standardized those, as well. I had little use for small footholds on my line in coastal Alaska, and mostly used Belisle 280s for otter, but when I needed a foothold for beaver, the TS-85 was the answer. I got rid of a bunch of other beaver traps of various brands and never regretted it.
