WWII U.S. Signal Corps BC-622-A Relay Unit

Original WWII-era U.S. Signal Corps Relay Unit BC-622-A. This aircraft radio/servo control component was manufactured for military aviation applications and is marked:

“SIGNAL CORPS RELAY UNIT BC-622-A C.Q.E. 156-DAY-45-SD”

Housed in its original aluminum case with multiple military-style connector ports labeled for:

• Radio
• Servo Gyros
• Auxiliary Function
• Battery

Front panel retains original toggle switch, breaker reset button, and labeling. These relay/control units were used in conjunction with wartime aircraft radio and automatic flight/servo systems and are highly desirable to advanced aviation, radar, and Signal Corps collectors.

Condition appears very good surplus original with light storage wear, intact data markings, and no major corrosion observed. Untested.

Excellent display piece or restoration component for WWII aviation electronics collections.
