Hello all - I just purchased 2 beautiful old 22's yesterday at a gun auction. A Marlin 39a from the mid 50's and an Ithaca 72 deluxe. They are both beautiful, however, the Ithaca has quite a bit of tarnish on the engraved receiver. I'm not sure what metal is used on the receiver. Should I try to remove the tarnish and if so what should I use. Any help is appreciated.
