I have seen a "GREEN APPLE" oxygen bottle in a very good condition with about 85% of the original paint/decals remaining.

The demand regulator is fitted but its minus the filling hose.

What is the value of this item? it is up for sale at £75.

What dates were these items used etc?

This is the only oxygen bottle I need to complete my collection.

On a closing note, is it designated a walk round bottle or a bail out bottle?

MIKE.

I'm assuming you mean an H-2 bottle.

These are a dedicated bailout oxygen bottle, holding about 10 minutes supply, and started to come into use in early-mid 1944, replacing the earlier H-1 bottle, issued from October 1941.
The H-2 bottle was still USAF issue well into the 1960s, probably later, and is still used by civilian high-altitude parachutists.

The cylinder itself should have the date of manufacture stamped into it by the neck, month and year. The cylinders were reused over and over, and the positioning of the gauge on the valve assembly was changed post-war. I'll have to check the wartime orientation.
The length of the pullcord varies too, post-war cords seem to be an inch or two shorter than wartime ones. The shorter pullcord leaves the "apple" underneath the flap on a pair of A-11 trousers.

Value wise..... I paid $25 for mine 2 years ago, including shipping from the USA, but I have seen them go for a lot more.

Alternatively, you could mean the green A-4 walk-around bottle, in which case ignore the above...... ;)
Hope that's of use,
PB

With your reply it looks like I don't know the correct nomenclature's for my bail out/walk round bottles?

I have a complete H-1 bottle and two H-2's (one perfect and the other 80% complete) and they both have the gauges facing below and in front of the "GREEN PULL KNOB". But only one as a wartime date and the other looks like it doesn't have a date at all?

I thought the H-2 wasn't known as a "GREEN APPLE" and the one I think was/is/maybe known as a "GREEN APPLE" is a green ball type about 6 to 8 inches across with a A-16 (A-16 if I'm correct) type demand valve on top. The demand valve that allows an A-14 demand type mask to snap onto/in it.

The best size I can estimate it against is the plastic ball that fits onto the end of a toilet cistern water valve ;)

So it looks like I should have gone to school the day we did oxygen bottles :D

I await your teachings Mr Bellamy.

MIKE.

Hi Mike,

Apologies, it was only after I'd posted that I remembered you already had an H-2 or two.
Both the A-4 and H-2 bottles seem to get referred to as "Green Apple Bottles", after the shape of the A-4, and the pull-ball of the H-2, hence the initial confusion.

Back to the A-4 bottle.....

The A-4 was certainly in production by 1943, and can be seen in use by early 1944 at least.
By 1945 there were "officially" only three types of walk-around oxygen bottle in use:
The A-4 with A-13 (AN-6022-1) Regulator (3-8 minutes supply)
The A-6 with A-15 Regulator (15-40 minutes supply)
The D-2 with A-13 (AN-6022-1) Regulator (20-50 minutes supply)
All three were of course to be refilled before flight, and during use topped up from the aircraft oxygen system when the pressure fell to 100psi.

All these three used demand-type regulators, so I don't think they were compatible with the earlier constant-flow masks like the A-8. That will probably give you a start-of-service date window.

All the best,
PB

And thanks to you mate, I 'found' the other one ;) Be good to put them together at some point, just in the process of trying to tidy it up a little.

Cheers Dave

I have one of those in about the same condition, Picked it up a few years back at a show, got the wrong though, thought it was early war but found out it was the later version.
