bz4736: Your 629-1 was probably made between July 1985 & November 1985. Serial number prefixes for those months were AHT & ALA respectively. Some guns were made out of date order however, so this cannot be guaranteed, but it's probably correct. To be certain you would need to pay $50 fee to the S&W historian Roy Jinks to have him research your individual gun.
