Hi folks, I've got some older guns from my grandfather that I am trying to get fixed up and looking nice so I can keep them in the family and pass them down. The one I am looking at right now is an older S&W Model 1955 .45 ACP. I'm not very familiar with gun finishes but I'm thinking this one is blued...or is it possible that the gun hasn't really had any special finish? I did some research and it seems that most older guns are either parkerized or blued and I'm thinking this one is blued. Can anyone tell from this picture? Also, it appears that some of the finish is wearing off in places. I don't think there is any rust however. What options do I have to get it refinished so it will look nice and last a long time? Any suggestions or advice would be great. Thanks!
