I just picked up a Model 28-2 today (4"). Serial number suggests a manufacture date of 1971-1972. It is going to need work as the sear is too worn to hold the hammer for SA fire, but I've got my smith working on it. I can't wait to shoot it.
Picked up my dream gun Saturday, S&W Military and Police (pre-10) with 2" barrel and original factory nickel plating. It was manufactured in 1950 and was only fired once before I got it. it was a presentation to a retiring police Lieutenant who fired it the day he got it and then put it up. I bought it from his daughter, he had passed on 30 years ago. I don't think he was much of a "gun person" and he just considered it a keepsake. I am now carrying it in a Minimalist holster OWB. It is very accurate out to 15 yards ( long range for my style of defensive shooting) and is a dream to shoot.
