Very funny
KR87 ADF ? I have one on the shelf above me, which looks like yours but slightly less tacky.
The indicator you have

Don't knock this - this equipment is legally required to be carried (the regs don't say "used") on all IFR flight in controlled airspace in the UK. And our CAA knows best; they employ only the best ex RAF navigators.
