So can someone tell me what they would have been used for?
Something tells me they're a VHF power tube.

Any application as a one-tube QRP rig of any sort? Any stories
about using them in the past? I've built a lot of little rigs over the

A lot of The Radio Amateur's Handbooks of the '50s and '60s had 892B
projects in them. The 1953 edition, immediately to my left as I write this,

push-pull class-C, up to 120 Watts CW or FM, and 100 Watts AM.

And the following fellow has gone to an awful lot of trouble to use two
829Bs in parallel single-ended triode mode in a stereo amplifier:
