The box and paperwork say 38 Chief's Special, Model 36 round butt, yet stamped on the frame inside the cylinder is mod 32-1. On the bottom of the butt is stamped R13278. Box says model 36, pin B, 2 in barrel, stock R, and serial number J977XX. Printed inside box is date April 15, 1955. So is it a J-frame model 36 or a model 32-1?
