[TMC] black crinkle MRK-1?

[Duncan Brown]

Interesting that DePasquale & Galione were the running the McElroy Sales 
Dept. at the same time that the were running TMC!!

The AWA Museum does have one piece of black crinkle TMC gear, but it is 
obvious that it was mfg. by McElroy.  It is the TMC/McElroy Morse 
Package Unit, Model MP-1A.  It is a Morse tape transmitter, receiver & 
perforator, all in a handy, portable box. Pictures enclosed.

Have Fun,
