I keep seeing these mid-1980's steel Scott Air Paks for sale. They are 2015 psi (+10%). They are about 19 to 20 inches long. They are referred to as 30-minute air supplies.
My questions:
1. Do they have a standard 3/4" thread? If not, what do they have?
2. Are they comparable to an old steel 38 cu ft in volume?
Thought they might make a cool set of vintage-looking doubles if I stripped the paint and put on a Sea Hunt harness. All input is appreciated. Mark
