[R-390] Single coil antenna relay--anyone seen one of these?

[Bob Weiss]

Have been working through the 1968 EAC "Rocketship" unit, and had to dig 
into the antenna relay to clean a dirty set of contacts, and straighten 
a mangled twinax connector. This unit has an unusual style of antenna 
relay with a single magnetic coil, and the neon overload lamp mounted 
externally.  Contact access is through a threaded access plug that was a 
real bear to loosen. Posted some pics at my Flickr page:
