Scott Aviation 22 Cu Ft Oxygen Cylinder and Regulator Assembly

Got this vintage Scott Aviation oxygen bottle and regulator assembly. It's a 22 cu ft tank, part number 801293-11. The label says it was manufactured back in 1983. It's got some wear and tear on the green paint as you can see in the photos, but the labels are still mostly legible. Not sure when it was last hydro-tested or if it still holds a charge, so selling it as-is. Might be cool for a collector or someone looking for parts for an older aircraft setup.
