hey sonny, I don't have direct answer for you, but if you look at the Alberta Cowboy Action site it has a few leads to follow. I have a few extras but not sure if your gun will fit. Your welcome to it though, it is just sitting in my leather kick around box. If you want to try let me know I'm sure we I can get it to you somehow.

Look on Amazon........ya, I know, but it's the only place I could find one for an antique and the price was great compared to the suppliers what wouldn't ship to Canada;  might be worth a look?
