After years of desire, one finally came into the shop I managed. Excellent, original condition, EXCEPT some numbskull had ground off the "Property of US Army" from beneath the barrel. Ugh! Destroyed collector value. Yet, it was simply in excellent condition, a serviceable large frame S&W in God's cartridge. I snatched it up, immediately.
I had several friends among the smiths at Cylinder and Slide https://www.cylinder-slide.com/, in my city of the time, and so made the M1917 into one helluva bowling pin shooter. New sights, Hogue grips (I sold the original, fairly minuscule stocks for nearly $100), a dual ball-detent lockup, and the matte finish. Of course I'm using modern full-moon clips rather than the half-moons. We opened up the rear sight groove, and installed a new front sight. That's a brass rod extending back horizontally. This old warrior resides upon my bedroom nightstand.
Norse, ACP only. PNW, that's a beautiful Smith, and it's history must make it a prized possession.
