Call S&W and they will tell you when it left the factory. It could have been made a week to a year before. 100-400 USD
ABOUT $250-$350, depending on condition. Pre WW II guns have a higher value, and "registered magnums" from that period with a factory rgistration letter can be worth MUCH more. PS- it is now known as a Model 28.
