Air 1: Second Price on ebay tends to run $20 to $50.

Splitter: First Apparently came in a number of configurations. Rarely seen on ebay. I have never seen one in the water.

You're basically looking at the late 1960s to the early 1980s with the second stage regulators. Nothing of fantastic value (sorry) but as far as good reliable vintage equipment, yeah the USD regs qualify. The SP Air 1 is old/modern and because of it's proximity to the SP Pilot, it has some historic value. The splitter is interesting, I've not seen one like it. The Sirius reg looks like a failed experiment from the dark old days of disco (1970s).

The Aquarius was my first reg, in 1973.

Parts may be an issue, but nice to go into your personal museum, or mantle.

Safe diving to you.
