Patrick,
I don't know the gauge, but I really like your gun. I'm not technically oriented, but your cocking system looks like a double hook, i.e. one in the frame and one dropping down from the rear lug to connect with it. That would be true to the date of production I mentioned. I hope you find barrels to fit. I could be completely wrong, but I think you need a set of barrels with a hook dropping from the rear lug. Others should be able to check me on this. I welcome being corrected, so long as you end up with the right info. Jent, are your barrels for a double hook gun?
