Hi, a long time lurker and a first time poster here.
I have 3 S&W revolvers.
1. S&W 686-3, 4 inch barrel, 6 shots, adjustable rear sight
serial # BHB80xx
There's also an engraved number that I do not know what it means, 07x
2. S&W model 19-5, 2 1/2 inch barrel, 6 shots, adjustable rear sight
serial # Bxx
There's also an engraved number that I do not know what it means, X86xx
3. S&W 638-3, 2 inch barrel, 5 shots, fixed sight
serial # CRU00xx
There's also an engraved number that I do not know what it means, 8xx
Thanks.
Edit: Just saw Rcmodel's post above, those engraved number must be the model number.
