Hey guys thanks for your responses in advance. I am relatively new to the forum. I am having a Colt 1928 built by John McGuire. He has already built me a 1919A4 and a 1917. I am looking to see if anyone can blue the gun for me for a decent price. John is willing to park it for me and I'm sure he will do a great job of that but I want to see if I can get it bluesd instead. If not I'll just have him park it. My local gunsmith doesnt have the ability or equipment to blue this gun. If anyone is near John in Tennessee or by me in the people republic of Illinois that's all the better as these aren't cheap to ship. I am close to Indiana as well. Thanks again for the help. I believe it has to be rust blued but what do I know.
