Found it on an auction site. S 62680, shipped in October '46. Not a pristine example for sure, but all matching, and there's just enough of the original marking remaining on the back strap to make me strongly suspect it's a WSP gun. Can't wait to shoot it--the action is smooth. Needs a lanyard ring, but the pin is there, and the serial has been stamped on the side of grip frame like similar examples I've seen.
