Another Peter B...welcome from this Peter B. The Colt is known to be the best made American double but was only made in Damascus which some fear. In that condition figure $700-$1100. It was also made in 10 Ga and in Grade 1, 1 1/2, and 2. Fine gun if you repair the wood. The Mod 97 used to be cheap but the cowboy action shooters have changed that. You did not mention general condition, but figure $250-650 for silver to high blue. The 97's are worth more than Mod 12's now.
