Frank Nichols is an ex Navy RM1 and is very familiar with the Navy's  
use of Teletype machines.
He is also a good friend which makes me very pleased.

Thanks to Frank Nichols and Greg Moore, I now know the wall box is a  
KWX-7
and how it was used - many thanks!

FYI - My Navy TTY web site now has a PDF of a 1977 NAVELEX manual  
listing
all USN teletype gear including cross-references to Teletype Co. models,
manuals, etc. Zounds, there are a million configurations!
Link is at the top of http://www.virhistory.com/ham/navy-tty.htm

cheers & thanks for the help,
Nick
