[MRCA] Signal Corps Kellogg carbon Mics

[Doran Platt]

I have two of the Kellogg carbon mics in excellent condition; cords and elements. I am told they pre-date the T-17. Someone suggested they were used with Jefferson-Travis and RCA equipment?  If anyone is interested in them, I am open for offers.  Thanks.
