Early radio control garage door controls,Barbar-Colman Doorman units for parts
Lot of early radio control units for garage doors openers for restoration or parts. These are all Barbar-Colman controls. There are some original instructions sheets and (newer) schematics. We're not sure that these are complete.
We're guessing that these are from the 1930s through 1950s.
There is a Barcal Doorman model B transmitter and receiver. The transmitter is marked T-17-1 and the receiver is marked RB-14-4.
There is also a Weather King control unit model EDRRT 4 (marked R5) with a bent plug on the connector.
