Kirby Morgan Superflow second stage- should I ?

Some of you may be interested to know that Scubapro regulators were used on some of the very early demand masks made for working out of a diving bell:

Bob Kirby describes in his book, Hard Hat Divers Wear Dresses, that the US Divers regulators were chosen over the Scubapro when the Dial-a-Breath was introduced because it was more easily modified. The USD hose came into the second stage housing parallel to the diaphragm and the Scubapro was angled back.

Do I remember correctly some Aquadine Mask and Pots used ScubaPro second stages? I tended a guy when I lived/worked out of Morgan City, La. who had an Aquadine Pot. We had a similar mask at the commercial diving school I attended.

Most of my commercial time (not much) underwater was in a KMB10.

I'm happy to hear your went ahead with the purchase and are enjoying it!

@couv I did a little search and come up with this (don't know if it is a modern modification) History General Aquadyne

Thanks Cameron,

I guess it helps to spell the name correctly. That is a more modern version of the "mask" we had at the school. I don't recall the adjustment knob being that long. Incidentally, the fitting in the band just above the demand regulator normally has a stem with an external knob. The diver pushes the stem in and put his nose on a V shaped pad when he needs to equalize his ears then pulls it back out of the way.

^^ is a dry helmet and similar to the one I mentioned previously.

Aquadyne was a machine shop in Santa Barbara that made parts for several of the small mask and hat manufacturers in the area, which were little more than part-time garage operations at that point. Their gear was well crafted but light on innovation. The mask had the hard seal -- open cell foam backed wetsuit material glued to the fiberglass. That design was abandoned by Kirby Morgan when an a abalone diver got his eyes sucked out of his sockets when a hose failed near the surface and the check valve failed. That accident inspired the soft seal on the Band Masks. See: Bev Morgan, Diving Industry Pioneer, Post #3, Innovations
