antique oak case tube tester, 1940s electronic tester for radio tubes

Antique radio tube tester in a good solid oak instrument case. This tester is a Tripolet model 1503 with the original instructions.

The case is quarter oak with finger jointed corners and measures 15 1/2" x 11 1/4" x 7". The case is in good shape, but the leather handle is broken loose on one end and the rubber feet are worn.

The wiring on the tester is worn and frayed. We haven't tested it and are selling for restoration or parts.
