WWII U.S. Army Signal Corps Control Unit

This is a radar control unit used in U.S. Army Signal Corps radar systems during WWII (early–mid 1940s). The “BC” designation stands for Basic Component, and units like this were part of larger radar assemblies used for:

• Aircraft detection & tracking
• Anti-aircraft fire control
• Experimental radar lab setups (as your plate notes: “designed for Signal Corps Radar Laboratory”)

This specific unit would have handled signal alignment, transmission switching (REC/TRANS), and power control, likely interfacing with transmitter/receiver units in a radar chain.

📦 Condition notes

• Original olive drab finish with honest wear
• Data plate is intact and legible (big plus for collectors)
• Knobs, switches, and front panel appear complete
• No obvious modifications or repainting
• Untested (assumed display/collector piece unless proven otherwise)
