Here is a Dacor R-3 Dial-A-Breath regulator. It has a small, rotating vane that can “feather” the Venturi to make it breath harder. Really old timer divers didn’t like easy breathing regulators, as they thought the ease of breathing caused them to use air more quickly.

Here is my Clipper, ready to dive. I put U.S. Divers Company hoses on the Dacor mouthpiece, and I had to wrap the mouthpiece with electrical tape to increase the diameter to get it to fit the USD hoses.

Here is one view of the second stage lever system from the side.

And here’s the lever system, top view. Note it includes the “Dial-A-Breath” vane, as Dacor kept that feature for some time.

Here is the Dacor R-3 with the “Dial-A-Breath” feature noted on top.

Here’s the Dacor ad for the Dacor R-4 double diaphragm. The Clipper is the same, without the double diaphargm.
