My bro-in-law said his shotgun was broken so I took it home. Looked like the firing pin was broken but after I took the gun apart I see it is fine. Before I even started disassembly a small pin fell out. I am pretty sure that it is not broke but just came loose. Now I have to get it back together and am having much more difficulty trying to figure out where each part goes.

I have been looking for a blueprint on line and can't seem to find anything. Do you know where I can find one. The gun is a 12GA single shot made by New England Firearms. It is called a Pardner. I do not see a model number.

Thanks for any help. Matt
