[Milsurplus] Curtis A-12 Aircraft

[Hue Miller]

TELE-TECH for Feb. 1949 has a photo of part of the Curtis A-12 aircraft.
Visible is a BC-AA-191, BC-AA-194, on top of the BC-194 is a box with
3 ceramic insulators, some kind of loading coil? Also above the BC-AA-191
some kind of frequency meter, much simpler than the BC-221, above this
is just partly visible, a receiver BC-229. On the wall of the airframe are 2
control boxes, one is simply off/on the other, two controls pointer and
knob, for the receiver. Squeezed in the few inches between the freq.
meter and the airframe is a key. How convenient for operating. No
place of course to rest your arm. My question, so this BC-AA-191
was paired sometimes with only the TRF BC-229? No, wait, if there
was a CW key, unless the transmitter was used in A2 mode, then
there had to be that CW adaptor for the BC-229, altho I don't
see- or recognize - it.   -Hue Miller
