Hey guys, so it looks like I have one of these on the way ( oh boy,oh boy !! ) and I didn't think to ask the serial number when I had the chance, or I'd just ask in the "S&W dating" thread. But, it is a model 15-4, so i'm guessing/hoping someone can tell me what years the dash-fours were produced.Thanks......

According to Supcia/Nahas' catalog, 1977-1982. The !5-4 was the last of the "pinned" barrels in the model 15.
