Here are a couple of photos of my MB Mk 3 setup:
Note that I'm using a third generation metal Calypso second stage for an octopus, and that I had a first generation Calypso regulator on the other post--mainly because that keeps the valve dry.
The MB Mk 3 conversion from the DA Aquamaster was done by Dan Barringer at Vintage Scuba Supply. I mention that because Dan was able to also rebuild my DA Aquamaster back up from spare parts, so I have both regulators without having to disassemble the MB Mk 3.
