Thermo-Quad metering rod measures
Here's a 75-1966 rod. I would have to go digging to see if I have any other loose one, or take one apart.
Did my best with my HF calipers, I suspect there are better ways and more accurate tools. I didn't match the economy step either.
Not sure how the midrange step works since there are only 2 parallel sections. Maybe the long taper midpoint is the midrange step?
