Be careful when you buy a replacement lanyard ring. It is NOT the same as the one for Victory models. The Victory rings are round and the 1917s are 'flattened', much wider than tall. The retaining pins are different too. The 1917s are much thicker than the ones for the Victory models.
Also, very NICE looking revolver for being over 100 years old! Everything looks good. The serial number stamped on the cylinder looks to match the one on the butt (both ending in '52') so original to the gun, the grips look good and solid, just a few dings on the bottom, there is a lot of blueing on the frame and barrel, and the color case on the trigger and hammer look good too. Congratulations!
My S&W 1917 had been buffed with a wire wheel sometime before I got it to remove some surface rust I guess. Flaming bomb Ordnance stamp is totally gone. So mine is a shooter.
