To All::





At the Chatham Marconi Maritime Center, home of (WCC Chatham Radio) we
have aMackay Radio MRU-19A, which is a complete ship radio station in one
unit. We wish to restore this to operating condition for museum display. We
wish to obtain the manuals and/or schematics listed below. Please advise if
you have anything listed available.

We would be glad to pay for any expense involved and the CMMC would be very
appreciative.



Sincerely -- William C. Ryder W1KL
