Here is the information you requested.

I found this bottle size to be just the perfect size for the 360.  It lays
down flat on the baggage floor next to the elevator pushrod tube. I place
the oxymisers between the pilot and copilot. A better idea is to use velcro
and attach them to top of  the seat back with the pilot's unit behind
passenger and vice versa.  I have flown using the system from 10,000 feet up
to 16,500 no problem.  I  never needed to fill the bottle on a round trip. 

One Trip 2 persons from Seattle to Chicago round trip. Another trip one

person from Seattle to Houston and back. Works great. If you do a lot of

traveling, the O2 really helps reduce fatigue.

I also have a filler hose to connect the bottle to a larger 4 foot tall oxygen tank.

Are you interested?  It is probably the best system out there for the 360
