[Boatanchors] WTB - Dow-Key Antenna Relay

I'm looking for a Dow-Key 12 VDC antenna relay in decent condition.  I'm 
rebuilding a Collins KWS-1 transmitter and will need an antenna relay 
when I get it on the air.  The original Collins design required a 110 
volt DC relay, which are just about as scarce as the proverbial hen's 
teeth!  As a result, I'm redoing the unit to supply 12 VDC to the relay 
coil in transmit mode.

I need a relay with the switching contacts that control the keying bias 
for the transmitter.  These are normally a set of SPDT contacts on the 
bottom of the relay, operated by a fiber plunger on the bottom of the 
relay armature.

Can anyone help me out?  Please let me know.

Thanks!!
