A friend of mine has 3 S&W revolvers he is curios about how old they are. I told him I knew where the smartest people in the world are when it comes to S&W revolvers .
The first one is a model 30 Ser# 6840XX
the next is a model 31-1 Ser# 1080XX
and the last is a model 18-3 Ser# 3K926XX
It does not have to be to the day just in the year. Thanks so Much .papabyrd
