My boss handed me a very old Shotgun in 2 pieces to-day which is covered in rust. Its been wrapped in newspaper about 40 years now and stored in his basement. He brought it back from Greece way back then. Its a single shot with a bolt action on it. What would you folks suggest in order to start cleaning this up as it does look like it can be salvaged. Very unusual bolt shape on it. I can send someone a pic of it but cannot seem to be able to post online. The stock is slightly cracked but is original to this gun and possibley can be saved as well. Any suggestions will be appreciated. It also has a very large trigger on it as well.
