Yep, a .32 Double Action 4th Model manufactured between 1896 & 1909. Serial range for those years was 209301 to 282999. As production ran at roughly 13,000 a year for the decade prior to 1896, I would guess 1896 or 1897.
Boot2U:
You have a .38 Military & Police Model of 1905 4th Change manufactured in 1915 or 1916. The 4th Change refers to the 4th minor design change since the 1905 major design change.
Your gun lacks the internal hammer block safety developed during WWII. if dropped it could fire, so leave the chamber under the hammer empty.
It also predates heat treatment of cylinders and hot loads could split or bulge the cylinder. Stick to standard velocity lead ammunition only, no PlusP, no +P+, jacketed or semi jacketed ammo. The sights should be regulated for the 158 grain lead round nose, so try that or 148 grain waddcutters if you wish to shoot it.
Value is not high, at most $350 in excellent condition, $250 if showing any wear. A dealer will offer you less than this as they will want to resell it at a profit.
The five inch barrel was popular back then as cops walked the beat, they switched over to 4 inch barrels when patrol cars became more common.
Several million M&P revolvers have been manufactured since the original introduction in 1899 and it is still in production today in a much modified form as the Model 10.
The grip is probably a square butt style, although I would need to see a photo to confirm. The frame is S&Ws medium 'K'frame. Spare parts would need to come from another gun,
