OK before I look, I'm guessing a bifilar winding. (twisted pair tied shorted at one end)

OK this did not produce any 'good' hits for me. Can you elaborate?

Strange. Google gives me 15,300 hits, most of which look relevant.

Nobody said a damned thing about precision resistors. We are talking about composition. His 0.5 ohm as well as any values above 2M Ohm are UNcommon.

Which yields two series connected inductors.
The winding method is a bit more complicated than that.

Seems a bit confusing.. in some references, that's called "Ayerton-Mather" (parallel inductive sections, one wound over the other) from their original 1892 paper.
"Ayerton-Perry" appears to refer (also?) to a construction of variable inductor that is essentially an Ayerton-Mather winding but where you can rotate one of the windings relative to the other (so Ayerton-Mather is the degenerate form of Ayerton-Perry?). It was described in their 1895 paper.

All this stuff was done in relation to work on ballistic galvos, early forms of AC bridges.

Part numbers, John?
Can't find 'em on Caddock site.

Here's the Agilent probe that uses them:

They use the Caddock MG series, 450 or 950 ohms. I could look up the exact part numbers on Tuesday when I'm back at work. The resistors work great all by themselves, saving about $2490.
