Cold War Field Telephones

[ChalkLine]

So, you've got yourself a settlement but the nasty OPFOR are monitoring your hand-helds? No worries, here's something to string between your bunkers.

Field Telephones.

Battery-powered hand sets appeared to all be able to run of external power, usually in the 3 volt range. Most phones seem to have a hand crank to enable ringing at the other end if not used with a switchboard. Nearly all these phones, you can probably assume it is all of them, are sound-powered. The only reason you need to use power is to ring the buzzer. If you don't have a dedicated switchboard, and let's be honest you won't, a simple task will be to rig up a series of switches that exclude or include lines for multiple use. In this case it's possible to have "party lines" of multiple phones.
