Older LEO's may appreciate this.... acquired a S&W Mod. 10-5 today, pretty good shape...
It was given to my nephew ( wife sister's boy ) He has wee one and didn't want it so he gave it to my BIL ...he in turned has passed it on to me

Nice, though has holster wear and was stored for some time in a in the waist band leather ... so it has some freckling
I disassembled it tonight, for though cleaning and it's soaking now in EEZOX®
Bore & Cylinder are excellent, tight and will be good shooter SS# date's it to 1969-70
I'll post a photo when it's presentable
