My dad bought this gun about 15 years ago off of a tenant who was behind on his rent for around 200 which was a great deal. A couple of months ago he asked me while he was redoing his will if there was any of his guns that I wanted but I told him my brother and I could work out most of them but I would like to have the 45 so today he brought it to work and gave it to me. It is a Colt gold cup national match 70 series. Most of the bluing is worn off but the rest of the gun is in excellent shape. My question is what is the value of the gun and should I try to have it professionally refinished or should I just leave as is. I have no plans for selling it I just plan on using it just for range shooting and just to keep around. Thanks for any input.
