[ARC5] Strange box - Pictures

[Neil Barnett]

My guess:
A very early (circa 1950) TV tuner connected
to a rebuilt ARC-5 IF strip.  The latter possibly
the 2830 KHz version from the 6-9.1 Mc unit.

What for?  To tune into the Police comms which
were on about 40 MHz in the 1950's and 60's.

The domes on top of the IF cans appear to be
vehicle frost plugs (not sure if that is the US term,
they rupture if the water freezes in the engine
block) , but why are they fitted?  To stop people
from tampering with the alignment?
