Smith & Wesson has some great close-ups on AMC's "Dark Winds" latest episode. Set in the early '70s, the Navajo police chief carries what I see to be a 4" Model 29 with a 4 screw side plate. Then with all the great close ups of him handling and unloading/reloading, I see .... OOPS !! ... rounded/inletted rear sight base (like my M629-4) , no firing pin on the hammer, and Altamont grips. DADGUMMIT (Heritage series?) ... I had been giving the prop "guy" some nice credit for having an appropriately early S&W for use out on the "res" .... Oh well
