Up for sale is a unique historical lot of vintage heavy-duty microwave radio waveguide components, heavily associated with the historic Cold War-era Long Lines telecommunications relay network.
These high-quality brass and silver-plated copper modular assemblies were engineered to demanding military and industrial standards by manufacturers like Western Electric.

* Visual Condition: Includes multiple interlocking modular waveguide blocks, junction points, and specialized tuning mechanisms.
The units retain their original golden-brass finish with typical patina, light surface wear, and vintage inspector tape residue from active service.
