I used to collect Ruger pistols. The only one I have left, that didn't get stolen, is an old model .357 Blackhawk. I bought it used, but it is in excellent condition, so I have been wondering how old it is. I contacted Ruger by email and was given a phone number for their Records Dept. I found out with one call that my gun was made in July 1969. If you are interested in dating your guns, give them a call at: 603-865-2424.
