Been out of the loop for awhile..heart re-furb..triple bypass and valve repair. But I am a sucker for PD marked revolvers and came across a S&W Model 10-5 .38 special today..SN#D1455xx. Square butt, pinned 4 inch barrel, minor holster wear. Marked on left side LOUISVILLE DEPT. POLICE. I have had a K.S.P. marked state trooper S&W in the past and this one today just spoke to me. It looks like it might have had a couple hundred rounds through it....locks up tight, case colors strong on hammer and trigger. Could tell some stories I am sure!
