I took a chance on an older 39A at a gun show. It was missing the firing pin and the butt plate was broken. Also, the lever wouldn't open the action unless it was forced to the side. I replaced the firing pin and butt plate but still can't open the action with the lever--any suggestions? I haven't gone beyond simple takedown--logic tells me the lever must be bent, but maybe I'm overlooking something simple? Would appreciate any and all help.
