Just picked up a 37 no dash 3in with serial no 3J31XX it has a pinned barrel and non diamond stocks with matching serial number. None of the reference books I looked at list such a weapon. Any ideas of year of manifacture.
Thankyou, every book I looked at said there wasn't a 3J prefex ever used. Mine looks just like yours with the 3in tapered barrel but with the tiny factory grips. Just noticed why my grips are smaller mine is a round butt.
