[Collins] Strange Relay..question?

[TJRachwal]

Hello all,
	While going through some old boxes of parts I ran across a T/R relay 
that is clearly stamped "Collins 410-0134-00" it is also stamped 
AEMCO Part R83-2624 (AEMCO stands for Automatic Elec. Mfg. Co located 
in Mankato, MN as stamped on the coil).  It has a bnc connector and 
two n connectors (all female0 as well as a set of external 
contacts.  What is this for?  Does anyone need one of these?
