some help please
I have an old service revolver that was left to me its a S&W model 10 5 with serial # D92xxx which i thought was odd.arent the SN's supposed to be 6 digits ? Its in decent condition and now lives in my gun case on display. any help with its history is appreciated. it was left to by a family friend who used to be a G&F officer. Thx in advance.
