Just Jim, if your gun is really a S&W Model one, 1st issue, 1st type, it's a super rare gun. Known examples can be counted on one hand. One of them, in average condition, just sold at the Las Vegas winter antique gun show for $40,000. Condition affects value, however in the case of these super rare guns, there are buyers for any condition. I suggest you have an expert examine your gun to be sure what is original & what may have been replaced, before placing it on the market, so you are sure what your are selling is the real item. Good luck, Ed #15
