[Boatanchors] WTD: Intercom Switches for Battleship

[eldim at att.net]

If you have a picture of this Switch, or the Intercom Speaker/Type/Model/PN, that it is used in; then that would be a leap in the puzzle solving.  I have boxes of every conceivable type of switch from our many years of dismantling electronic equipment.  So, as the saying goes, "A PICTURE IS WORTH A THOUSAND WORDS".  The real puzzle is INTERCOM "XXXX".  I'm sure that this item's classification has been downgraded so that it's real name and part number can be safely released with retribution or prosecution.
The Centralab PN:  2BFX6977 does not cross in my Mar 2005 FEDLOG Data Base.
I'll continue to do more research as soon as some more info becomes available.
