WWII 1950's Era Bomber Large Oxygen Tank - $100 (Prescott)

Pretty sure this was brought home by my grandfather.
He was an aircraft mechanic in Florida during WWII.
He kept the trainer planes up and running.
Has a good size dent on one end (possibly why they let him take it home) and nipple is bent.
I know it holds air because my uncle used it for years as a portable air tank for filling his equipment tires.
