I also bought a pony tank that fits nicely in a helmet bag with the fill

Hi Doc.
I am from an area where everyone who lives here is known as a "good ole boy".
The color on the high pressure bottles around here are the color that happened
to be in the spray gun when the guy pulled the trigger that released the mist.
There is a grey and black tank that is filled with compressed air instead of
nitrogen. A yellow and green that is filled with CO2. An argon tank that who
knows WHAT is inside of it.
So buddy.... unless you DO test it, or know for sure who filled that bottle last,
you are STILL at the mercy of the folks at the FBO.
mgb
p.s. The local dive shop will fill any bottle with compressed air that you bring
in as long as it has a valid test stamp. They could care less what color
it is... after all, diving tanks come in any color that you want, starting with
blue. The only people I have seen get really serious about tank color are
people that work in the local hospital, but hey.. they are not good ole boys.
p.p.s. We could always put a canary in a box and spray some gas in it's face
and see what happens! Worked for the coal miners! :-)

There is one way to absolutely know if what is in the green bottle is pure

You'll get the light show of your life if it is pure 02. If it is

I for one do not have the gonades to do that and am not looking for a
Darwin Award so I'm not going to do something that stupid.
Now a more common sense way would be to look at the green bottle, say "that
is a GREEN" bottle with a yolk on it. That must mean the it has or had 02
in it and it will probably do some serious damage to my airplane or me if I
put it in my fill port. The only way you know what goes in your airplane is

The last strut pump I saw was not very large. Smaller and lighter than a

hardware setup already attached, you would only have to plug on someone's shop

loss (sudden or otherwise) of its pressure.
