Thanks Mark, it was a fun rebuild and I'm thinking of doing another sometime.
The serial # on the 2nd is- 76 29012, so I guess its from 1976. Thx for the info on the serial #. the serial # on the 1st stage is 615674. Is it possible the first # on the 1st stage stands for the year 1976?antique diver wrote: ↑Wed Jan 31, 2018 9:33 pmThat's a nice looking regulator, and I think you will like the way it dives. If it needs a little boost there are shims for the first stage spring to raise the IP to get it breathing about as easy as anything else since it was made. If you ever want to convert it to a Calypso-J I have new old stock factory kits. (but then your pristine looking Calypso IV decal wouldn't be correct).
BTW, the first two digits of the serial number on the second stage body designate the year of production. I'm curious what year that is.
Back in the early seventies I sold a lot of Calypso J regs. Seems like they were going for about $170 back then. One of them was sold to the owner of a local Army-Navy surplus store, and he never used it. I saw it for sale in his store in the 90's and bought it back for $25. Still in my collection... still never used, but I have another one almost as nice that I dive occasionally.
I don't know the details on the first stage serial number. Hope someone can enlighten us if it has any meaning.
Cool!
Good idea. I'll get a Calypso out later this morning to take a good look and measurements of the clip, then check the closest part from McMaster.
