Yah, that's right... radium. I had forgotten about the factory
worker exposure, you are absolutely right, the people painting the
dials got the stuff all over themselves (direct skin contact and
ingestion from dust/fumes) and it eventually killed them.
(this was before the effects of radiation were fully known and
appreciated).
In anycase, a friend of mine has a couple of these dials and
the Geiger counter goes crazy (on its most sensitive setting that is)
when you place it near one. A few feet away and its zippo. Right up
close and its buzzing like hell.
I'll bet you can find cheap WW2 bomber instrumentation on ebay.
