My military "boatanchors" collection includes :

a Wireless Set (Canadian) No.19 Mk.II, and two Mk.III's,
an RCA AR88LF communications receiver,
an R390A/URR communications receiver,
an AN/ART-13 HF transmitter (with dynamotor and O-17 LF oscillator),
an AN/ARC-502 VHF transmitter/receiver,
and most of the components of an AN/APS-4A airborne X-band search radar.

Restoring and operating vintage military radio gear is, for me, the most enjoyable aspect of amateur radio. Aside from the challenge and satisfaction of restoring a small bit of history, some of these rigs have quite an interesting background. It's also fun when you recognize one of your rigs in an old photograph or film clip.
