Yeah Luis H, a bit like me. It was a gift from a guy after I gave him a spare DAN 02 kit handwheel. There is a stamped outline of Australia in the rectangle under the outlet. There are no other markings.
Australian Divers (Spiro) Pty. Ltd.Melbourne. Australia.
This name eventuated after L'Air Liquide "bought" the single hose reg design from designer manufacturer in a garge, Ted Eldred, Breathing Appliance Company Melbourne, and went off in search of their billions.

Interesting choice Phoenix, how did you decide that?
Cheers Emile.
