Again another interesting exotic 1st.
It came with two Coltri Sub 2nds, so probably it's a Coltri Sub 1st, but I can't find anything about it in the net.
It's a fascinating design in that sense that it is an inline balanced diaphragm 1st, but you can move the HP (2 ports) outlet part as well as the LP turret (4 ports), really cool.
I don't remember that I ever have seen that type of design and I wonder why nobody tried to copy it.
Components and chrome look pretty good, just the SP DIN Connector ring is a bit weird.
Balancing works very well (only 1-2psi difference between full and near empty tank) and it has a funny shape.
I don't have too much hope, but maybe someone here knows more about that model......

No idea what it is but it could be a winner for the useless complications award.

Looks like a pretty standard diaphragm design to me. Looks to have a swivel...
