Unusual scuba regulator

[divernelson]

My neighbor was showing me a box full of regulators and this one was the oddest one there. Any info would be appreciated.

It is a Mark -1 sold by Diver Master. It is a converted military o2 reg. Just like the Sea Horse,Supreme Divers and Palleys o2 converted regs.A friend of mine has one. His looks rough no hoses ect. Still very hard to come by.I have most of the Dive Master catalogs.It was offered in there 55 an 56 only.They also sold the MK-2 double hose. Dive Master was owned by the late Vern Peterson.

I would like to thank Karl from Scubamuseum.com and Mike Lev. for their info provided on this Vintage treasure. My neighbor has decided to hang on to it for a while and will not be selling any of the other regs.
