Tank Checker and Regulator identification

[owlbill]

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

Still looking for info on this pressure gauge.

Hi Owlbill,
Thank you for your interest.
You might be better off checking some of the vintage scuba websites and forums. They do a better job keeping up on these matters.

Hmm.... I was hoping for more LOL.

Guess I will check elsewhere. It's the Hamilton, Canada marking that has me stumped.
