I have been of the opinion that my .22/.32 Hand Ejector was manufactured in 1925 due to the serial number (409001). Now when reading the Catalog (4th Ed.), it states that the S&W logo was moved to the right side of the frame in 1914, mine is on the left. It also says that the stamping Made in U.S.A. was begun in May 1922, mine is so stamped. Also in 1920 they began heat treating cylinders at about SN 321,000. The SN of my revolver is well beyond this. OK, anyone who can explain all this?
