[Milsurplus] Holiday Puzzle

[Michael Bittner]

I recall buying a Homing Modification Kit (MC-619) for my BC-611 from J.J. 
Glass Co., back in the days of the big mil. surplus stores in downtown Los 
Angeles. Besides the DF antenna (AN-190), Antenna Coupling Unit (BC-1387), 
HS-30 earphones, extra earplugs and manual (TB 11-235-8), the kit included a 
thick bottom cover (called a Jack Plate) to replace the cover on any BC-611 
with a thin bottom cover. The manual says to discard the thin bottom cover. 
The thick cover had a phone jack to allow the included phones to be plugged 
in.
