That' so cool! I love watching old movies and seeing something that I own. For me, it's usually a telephone.

haha yes its fun to point out things like that. i do it myself with all the old stuff i've collected.

Not to be picky, but to just clarify. Painting the tanks yellow means breathing air (21% 02 in air), (100%) 02 tanks are green.

Also note that low pressure (approx 0 to 425 psi) bottles are yellow with black nomenclature and high pressure bottles(300 to 1600 psi) are green with white nomenclature.

The USAF is still using the 'walkaround' bottle design used in WWII! Part of the preflight on my aircraft is to check their pressure and fill them if they're low.



And the Enola Gay's oxygen system:



KC-135s still use these bottles in their oxygen systems, as well. There's a rack with 12 of them in the back of the fuselage over the boom operator's compartment.

kpreed, on the flightline, we filled the 135 from carts with green high-pressure bottles(with a regulator, of course). All of the bottles inside the 135 are yellow, and the walkaround bottles are filled off of the aircraft's oxygen system. The regulators on board mix the oxygen as needed, you get 100% on the emergency setting.
