There needs to be a short back story to this.
When I graduated from college, the first job I had was as a field engineer for a small but somewhat well-known process control and measurement company. They had some interesting gear: strip chart recorders, temperature monitors with LED displays, pH and thermocouple hardware. But ultimately, I realized the job was a dead end for my engineering training so I went somewhere else.
As a tip of the hat to my old company, I decided that owning a small memento would be a nice thing, and I could legitimately say it was something I could have had back in those days. Found this on the Bay for $20 and decided it was too cool to pass up. It has about a century's worth of dirt and grime on it, and there's at least one duff connection in the wiring, but once it gets cleaned up it will be a nice thing to have sitting on the lab bench. I did manage to test the 1-10 Ω range and it was definitely within 1% accuracy.
