I have a colt series 70 government model that does not get shot much and just sits around. Based on the little bit of research I did on the serial number it looks like it was made in 1978. I got the grips after I acquired it and I do not think the mag is a colt. Everything else seems untouched and correct for the period / model but I obviously cannot be sure if everything is original to the gun.
Will sell for $
