For removing the rust. I would suggest Blue wonder gun cleaner and 0000 steel wool. You heat the gun up with a hair dryer until its hot to the touch and aply the gell cleaner comes in a tube.The heat opens up the molecules and the cleaner penetrates in and releases the rust. The steel wool in 0000 will not harm the blueing scrubs it off.
Its very good stuff I have used a number of times.
Once you post your pics the collectors over there will post pics of theres that you can compare also.
This is a great forum thats why i come here but if you want to talk to members of the smith and wesson collectors association who appraise and buy and sell and know smith and wessons inside and out those two forums are the place to go.
