It's not a Model 10. You don't list the serial number (it should start with a 'C' and is found on the butt). It pre-dates model numbers by a few years. Some call it a pre-Model 10. The factory called it a .38 Military & Police Model. That style debuted around 1947 (post ww2 short action) and the upper sideplate (which yours has) was deleted circa 1957 just before the Model 10 became a thing.

It would look a lot better with correct post-WW2 diamond magna stocks. Since a good set of stocks are worth $50 or more, you can subtract that much from the value of the gun.
It's worth around $300 give or take. It would probably start out higher on a gunshow table or pawn shop case but.
It should make an excellent shooter!
