Welcome to the Forum! According to the "SCSW 5th Ed.", your Model of 1953 .22/32 Target revolver should be a fairly early version (1953-1954?) since the s/n's began at 101 and continued to 135465 (1953-1973). S&W named these revolvers the "Model 35" beginning in 1957. Yours should have 4-screws on the frame and a 6" bbl., along with diamond-center walnut stocks. It should also have a flat latch cylinder thumbpiece. It is possible that only 8350 units were manufactured, but I can't verify that number. Hopefully a few Forum members that are much more familiar with these models will chime in and help answer your questions.
