Hi Dave,

I finally located my copy of THE NAVIGATORS' INFORMATION FILE (1943) to look up
the oxygen mask designations. The demand mask was listed as the latest in 1944
was called the A-10.It is the one we used in combat. The "spit bag" mask we
used in training was continious flow and had to be set for the altitude at
which it was going to be used. It came in three models. We used the A-8B. Hope
this helps.
