    OK, so three or four sections of approximately equal length in the varying resistance zones, right?

    If it's not too much trouble, a resistance measurement across 10 turns in each section would be nice to have.

    Yes, exactly.

    I'll see about getting readings on a couple of turns.

    "Tip". Literally. The old RCA VoltOhmist VTVM has probes that used Victrola-era ground steel "phonograph needles" in a collet-clutch.

    Helps to have that precise a contact when vetting low-Ohmage wirewounds.

    Few modern probes have that, as the buggers will draw-blood or slice tissue just as easily as pierce insulation, surface coatings, or corrosion!
