Not sure what you are asking for. Would you clear it up for me. I think of a complete list as every model and design from conception to present. However, you then ask for any version or any year.

I'll help if I can.

Here is the first Calypso first stage. It was the first balanced diaphragm single hose regulator that I am aware of. The second stage had the exhaust in the middle of the diaphragm and a metal exhaust T on the front cover. I don’t have a picture.
This Calypso is from the late 60’s

Here are the Calypso from the 70’s. They were flow through balanced piston first stage.
Some of the models were the Calypso III, Calypso IV, Calypso J (with a built in reserve mechanism), etc.

The second stage for the 70’s Calypso was the fairly generic US Divers metal second stage similar to the on this Conshelf.

Someone else may be able to help with the newer models.
