[CW] MAC Key

[D.J.J. Ring, Jr.]

There was at the end, McElroy Electronics, Shirley, MA (still in
existance, making terminals and other electronic components).

McElroy Electronics, Boston, Mass. (now Shirley, Mass.)
Telegraph Apparatus Company, of Chicago, Ill.
Telegraph Apparatus Corporation, of Chicago, Ill.


Some identifiers used in military contracts:

CAPH    Telegraph Apparatus Company. (Ted McElroy, Joe Goode and Frank Bascomb)
CAPZ    Telegraph Apparatus Co., (CORPORATION ???)  (Ted McElroy)
CMK      McElroy Electronics  (T.McElroy)

I have always wondered if the partnership TACo (CAPH) of Ted McElroy,
Joe Goode, and Frank Bascomb incorporated - I never understood the
tags of "NOT Inc.!"
