That's good info...I didn't know that.  I wonder if there have been any observed with Signal Corps stamps on them like most of the AVT-112 sets have.  I thought (without any real basis) that the AVT-111 was most likely an immediate post-WWII commercial only set, with no military history.

I was given an AVT-111 and an AVR-100 receiver and was told they came out of the same aircraft, but that info could have been bogus.  The AVR-100 seems right for an AVT-111 except for the fact that it is designed for A/B battery operation, and not a vibrator power supply.  I know RCA made a A/B battery-powered version of the AVT-111, but I don't know if they made a vibrator-supplied vesion of the AVR-100.

I'm fond of these old light aircraft sets.  I especially like the receiver-transmitter combos, like the GE ASB-1B, the Hallicrafters CA-2, the Harvey-Wells ATR3, the Bendix PAT-40/PAR-70, etc.  In particular, the ASB-1B seems particularly well-designed.  The competing CA-2 and ATR3 are very cheesy by comparison.

In a related area, has anyone ever heard of a smaller beacon band receiver than the Bendix PAR-3?  It's a cube about 4.5 inches each side (smaller than the "Airboy), and cost $31 new 55 years ago.
