I am attempting to put together an operational ZB-1 homing system, and am looking for the Western Electric CW-29093 switching relay that was specific to the ZB-1 homing adapter. This relay is almost identical to the CW-29173 switching relay used with the R1/AR-2 and ZB-3 homing adapters, but used a different type of coaxial cable than the later homing adapters. I do have a ZB-2/ZB-3 CW-29173 switching relay I'd be willing to trade for the earlier CW-29093 relay. You can contact me off list. Any help is appreciated.
