i have a fellow machinist who has his ffl. i buy from him occasionally and he gets all kinds of dealer flyers. one is szanders i think. anyway, he had listed 3 1950's era government models. all in cosmoline. 2 lnib and one unfired. original boxes, paperwork and all c series prefixes, which would put them in the 1950's. if i remember correctly, the price was about 7500. i'm not knowledgeable enough to know if the price is fair or not. but wow, wouldn't i like to have a 60 yr old unfired GM. is that a good price? oh i forgot. consecutive serial no's.
