As Jack says, It's not a Model 10, however collector's call it a Pre-Model 10, as 10 yrs. after this gun was made, S&W adopted the Model number setup and call the gun a Model 10. Correct name for this gun is a Model 1905, 4th change. I would say the gun is probably worth about $300 range, if it's in good mechanical condition. If what you are trading for this gun is something in the $300 range, then it might work for both of you. Ed.
