Guess I am late to the party. I brought along some of my favorite S&Ws.
Let's go oldest to newest shall we?
Pre-14 - K38 Heavy Masterpiece:
Model 14 - Red Post front sight (Letters):
Model 14-1:
Model 14-2 (Dayton gun)
14-3: (Letters as Single Action Only):
FYI - I am still looking for a real nice pre-14 narrow rib and a nice in original box 14-4 8 3/8" gun to round out my collection.
