WWII-era U.S. military Wave & Power Meter Set TS-107/TPM-1

Original WWII-era U.S. military Wave & Power Meter Set TS-107/TPM-1, made by Western Electric Company. The data plate identifies it as U.S. property and marked TS-107/TPM-1, with frequency coverage listed as 500–1500 MC. The unit retains its original olive-drab transit case, front panel controls, Weston Electric milliamp meter, moisture/fungus proofing stamp dated January 1954, battery compartment marked for Signal Corps BA-27 or Navy 19014, and multiple original accessories stored in the lid.

The lid compartment includes coaxial leads, connector fittings, frequency meter cavity chart, and circular power converter/calibration disc. The panel includes meter/video connections, crystal input, frequency meter input/output, coarse/fine controls, galvanometer sensitivity, measure frequency/power controls, test/balance switch, and crystal/thermistor storage.

This is a very desirable WWII radar/microwave test set for collectors of Signal Corps/Navy electronics, Western Electric military equipment, radar test gear, microwave measurement instruments, and early RF laboratory equipment. Complete-looking accessory sets like this are much harder to find than loose meters or stripped cases.
