U.B., Like Dean said, tell us more about what you have & someone will tell exactly what it is & when it was probably shipped from the factory. What type of grips? Hard Rubber or wood or?, where are all the serial numbers stamped? Barrel ears? Latch? butt? cylinder?,etc. What type of finish, and how much is left? length of the barrel ( measured from the front of the cylinder to end of barrel), Where on the gun is the Smith & Wesson logo stamped? Exactly what is stamped on the top of the barrel rib? Take off the grips (carefully) and tell us every letter, number or symbol stamped on both sides of the grip frame and last = Is there any number stamped, scratched or penciled on the back side of the right grip panel? Fill us in on all of the above and your prayers will be answered! Ed.
