Vintage Double Hose

I have a decorative use for this on another project, but I want to make sure there is nothing special about it before I cobble it up.

This might be an option B.

Those are both regulators that you don't come across too often. Do you have the 2nd stage for the White Stag unit? The 2nd picture is an original 1959 Sportsways Waterlung unit. You'll see them from time to time, but not that often. The 2nd generation "Model B" Waterlung is plentiful. The unit you have there has pipe thread fittings and the original red hose. The 2nd stage exhaust tee should be a white/opaque color.

The sportsways has a reg matching your description with a low serial number if thats what the number is. I dont have the white stag second stage.

That is it, early Waterlung like the one used in Sea Hunt. I would save it!

Well I guess I'll put those two back in the box. I have an old mk2 and another sportsways that doesn't look like anything special I can use for this project.

The sportsways with the red hose looks like with a new hp seat and the over preasure valve cleaned, it would work.

So my only other choices for my project would be a MK2, a Healthways Ive used on my pony bottle, and another sportsways.
