Went to a gun show today in Maine and traded my GP100 for this beautiful Super Blackhawk 44 mag, 5 1/2" barrel. Traded even, he included a box of fifty 265 grain ammo and sold me two additional boxes for $20 dollars apiece. The serial number dates it to 1986. Came with the matching box..no paperwork. He was not a dealer but had a table set up with his own personal guns. The bluing is gorgeous, not a scratch on it anywhere and its as tight as a new gun. Could someone tell me if these sights are original. Also the gun has a great plum petina to it, especially the loading gate. I did notice when out in the sunlight it differs from the frame which doesn't have the same plum color. Is this normal or is there a chance the grip frame is not the original. Felt I made a good deal, what do you folks think? The serial number is 8564xxx. Do I have the correct date? Are they as strong as the new SBH? Sorry for all the questions......I'm excited!
