Smith & Wesson Model 29 revolvers, commonly referred to as "Magnum," were produced starting in the late 1950s. Serial number 162469 would likely place its manufacture in the early 1970s, as S&W began using a different serial number range around that time. For the exact year, consulting a detailed S&W serial number reference guide or database would provide the most accurate information.
