I picked up a Nickle SAA yesterday and I am not sure what I have. I am a novice at this and I would appreciate some input. I will try to add some pictures. This frame has 3 lines for the patent information and the Horse is inside a circle. It is a black powder style frame. The serial number is 3 digits with a letter -a number - and a letter stamped above the serial number in a slightly different font. It is a very nice gun but I am wondering about some of the markings. There is no caliber listed on the barrel and it is listed as 44-40 on the hammer end of the cylinder. Inside the grips the same letter-number-letter sequence is marked and the grips do say Colt Hartford CT inside them. I am not sure if this is something someone has made from a mixture of parts or if it is an old gun that has been refinished with parts replaced or if it is a new gun with some type of custom work and custom serial number.
