Is there anywhere one can get replacement jaws for this trap? Any equivalent that would work? thanks

From almost all the big trappin stores has them, like F&T and so on.

Check with Sterling Fur co. AND possibly a slightly modified #2 Bridger or Duke sq jaw MIGHT be fit??

Contact Cumberlands NW Trapper Supply in Owatonna, MN. They have just about everything you’ll ever need

Coach Mike's (MChew's)advice on Sterling Fur is good as I have found parts for all types of traps with them at good values. MTP also has a boatload of Bridger parts too. And to answer the question. The Bridger square jaws fit fine. Might as well change them to high (Bridger) levers and order them too while you are at it. i have done several dozen conversions from original Montgomery to Bridger OS jaws and levers and like the results.

Don’t mean to hijack but I’m needing a couple pans for the old Montgomery dogless square jaws. Anybody have these??

Wife,
I have several #2 square jaw Monty low levers. To confirm, you are saying that the Bridger #2 levers work on the old Monty's? I know the #3 levers work on the Monty #3's. If the #2's fit that's great info.
Do the #2 Bridger levers come up higher that the original hi levers? Thanks.
