This 40+ year old regulator recently came into the shop for service. A rare Poseidon Odin first stage with a 4300 psi rated yoke! The second stage is a Jetstream 2nd stage currently still being sold by Poseidon & used by United States special forces & discerning divers the world over. Ice, deep or contaminated water? Bring it. You want high flow? This system has it & then some. It tuned perfectly & breathes as well or even better than most air delivery systems today.
What are the chances of getting two Independant customers at the same time wanting O2 serviced twin steel 72 cu. ft. cylinders & manifolds, powdercoated white & filled with Nitrox? Not all steel 72’s are alike, some made by Pressed steel tank, Norris to name a couple so there are slight subtle shapes & size differences as you can see in this photo. Why invest good money in these old tanks? 2250 psi rated Steel 72’s were made with a much better steel alloy than newer high pressure cylinders of today, always pass hydro if cared for, can always be filled to capacity, their buoyancy is great and 72’s make an awesome set of double’s. You could say that these doubles are more than worth the trouble’s! 
Mark Spencer a Avid Historic Equipment diver and INSTRUCTOR recently had us refurbish a set of Sportsways twin 1880 psi rated 38 cu.ft.cylinders from 1963. Mark is current champion of a International historic diver competition based on authenticity & working order of Scuba equipment from the 60’s! 
New asphalt coat & paint striping on our parking lot! MM Good!
Most are either 3/8″ for L.P. 7/16″for H.P. & 1/2″ for the classics on older U.S. Divers and duty built Dacor. Mostly chrome plated brass but there are Titanium & Aluminum as well. Some same sized port plugs take different size O-rings, have different O-ring lands & overall differing depths! Use caution mixing & matching between manufacturers. This photo represents longevity, we know not many Dive Centers can produce a supply quite like this!
