I have a tank pressure checker that looks like the ones in the 1960's era Aqua Lung/US Divers catalogs. This gauge though has "Hamilton, Canada" on the face. Any idea when that would be from?
Also, I have a couple of Calypso regulators (model 1030). Is there a way to tell what year they are from by the serial number? I know they are 1961 to 1964 but I am trying to get more exact info if possible.
Thanks,
Bill
