Hello all. I picked up a S&W Model 48 the other day a guy inherited. From what I found in my own research is its a 1960 model based on serial number. Had a gunsmith friend check it out and replaced a cut spring with 11 lbs new spring. He stated this gun is a true 90-92 on condition. 8.25 barrel couple scratches minor tho but original bluing is beautiful. Would love to keep but honestly bought as an investment. I have seen these anywhere from 600 to over a grand but I do not have original box. Thinking of advertising for 850 obo and wanting some educated S&W input from you guys. No this is not an advertisement for it here I read the rules. Honestly just need some smith guys input.
