Dustin and Graham have given you enough of a warning to understand that this isn’t going to be a successful guessing game and not to take a dremel tool to any of the bits inside this old gun. Seeing how the action sits with the lever open makes me wonder if the ejectors are in time, or, if they try to eject when the gun hasn’t been fired? Shortening anything isn’t going to fix what might be honest wear or past bodgering the gun may have suffered.

Might be very wise to enlist the services of a good gunsmith at this point. Which, will likely add significantly to the final cost of the gun.

So it goes at auctions.

Best,
Ted
