Thanks for the replies. Everytime I try to post a picture it fails but my favorite is my only one, my Smith and Wesson Model 29 44 magnum! 6 inch barrel, wood grips, blued finish.
I have a 19-3 that looks just like that gun that was a police trade-in and is marked "W.P.D" followed by the number "142" (both visible above trigger). It even has the same grips as the one in your pic. I'm thinking about sending it to S&W to get reblued.
Has to be .45 Colt of course and blued... and a Single Action to boot ... So the favorite 'right now' is the .45 convertible flattop on the left in following picture.
