I recently picked up a pre '55 colt cobra that had a horrible nickel finish job done on it. While I am not concerned about the looks, it appears it wasn't done right which caused some parts not to fit right, and they didn't plug the barrel so there is flaking nickel in the bore. I am guessing it would have to go to a colt smith and then to the refinish shop so it could be properly disassembled and reassembled, but I am not sure who to use. I did reach out to https://www.customshopinc.com but they were kind of shitty to talk to, and basically told me I was looking at up to $1500 to get it refinished and in working order. While I am not totally opposed they stopped talking to me after they quote when I asked how to proceed. They also seem to be some kind of celebrity shop, so that has me a bit worried. I thought about Frank Glenn, but I didn't see any kind of refinishing service listed.
