Westinghouse WRT-703 Audio/Video Chassis
This chassis is identical to the RCA TRK-12. However, it has no serial number other than a pencilled "No. 10" on the bottom. It is stamped with "WRT" in several places.
The 5 channel tuner is on the left side. The potentiometer with the long shaft is the contrast control.
