I need a microvolt ammeter!
I'm trying to measure current using the built in resistance of my inverter leads with in line circuit breaker, but the resistance is too low to measure using my standard meter.

Muscians might want that Attenuator. They use them for cranking up tube amps, but not powering the speakers that much. So you can practice or record with the tubes being pushed but at low volume. They would need some adaptors but it could be done.
That’s a 500ohm unit. May not be useful for audio line.
Any dates on their long expired calibration stickers?
7/16/84 on the chart recorders. The rest is missing or never had any.
The Ronnie Raygun administration was a big booster shot for the semiconductor industry, especially mil/aero divisions. A lot of new "modern" equipment was purchased in the 1982-on timeframe to replace the old, manually intensive crap. Anything that was not programmable via rs232 or ieee488 was usually relegated to the lab, dumpster or a dark storage room and forgotten.
HP came out with really cool multicolor pen 2D plotters (for electronic test) about that time - ieee488 bus, finally we could capture waveforms, scale, superimpose and plot them out on paper (we had to set up oscilloscope with a Polaroid camera before that). B/W pictures only because color was really expensive. Lol!
I have a tek465 w/camera sitting here.
