Armed with that, I searched for Bauer, 1980s and best guess is it's a UTILUS, CAPITANO, or MARINER.

The size of the first stage cylinder and configuration of the valve head would determine which is which. The Utilus would have a small cylinder and the valves would be conventional, discharge would be a hex nut (32MM) in the center of the head and the inlet would be screwed into the underside of the head. The Capitano would have the same type discharge valve, but the inlet valve would be a plate with a large center hole and multiple small holes around the circumfrence and lays directly above the piston. The Mariner has a reed valve plate and the top of the head is flat.

If you can post a picture of the first stage, I can identify it by sight.
