My first horizontal 1st stage with one HP port and three LP ports

Unusual Yoke rated to 4000psi / 280 Bar

The three LP ports

No identification on the 1st Stage other than on the plastic knob

The 2nd Stage

Other view of 2nd Stage

It's tank contents gauge
Tried it first in a sink and for a few breaths it worked but then it started to bubble air through the front of the 2nd Stage - diaphragm rotted

However, in poor external shape I had a Dacor set of regs and the diaphragm was an exact match.
Used it for 30 minutes in a nice warm swimming pool and it seems to work fine but was wondering if anyone knows any more about this model.
It also came with a Typhoon branded tank made in 1978 in a nice shade of orange without a single test stamp on it.
