[Boatanchors] Need info on a keying relay

[Michael Tortorella]

Fellow BAers, I am trying to figure out the workings of a vacuum relay that
looks like it is a T-R relay from some Navy BA.  It is K102 from whatever
the BA is, and has the numbers CZR-410-0008-00 on it, and catalog number
G-32877-A.  The glass relay is T-shaped and mounted to a gray metal case
about 4"x5"x5" or so with the relay sticking out the top.  Has anyone seen
one of these or have any info on pinout for the control socket?  Thanks and
73, Mike W2IY

PS - Johnson Viking Courier still for sale, looking for offers, photos
available.
