Vintage HP test gear, talk about bullet proof! Rescued and restored from sitting in an inch of water in the bottom of a scrap bin. Oscillator, attenuator and an AC volt meter with dB scale. Everything meter you need to tune up cassette decks in a telephone test set case. Disassembled, cleaned, repaired rotted traces, cleaned every potentiometer and rebuilt the 4 strange 6V Ni-Cad battery packs (5 x 1.2v stacked NiCad button cells) in the Oscillator and the meter. Still smells like sour milk for some reason?
