I have some telecoils (magnetic antennas) for body-worn hearing aids
that have 3600 turns of 0.05 mm wire. That's between 44 and 45 AWG, or
47 and 48 SWG. These were made in Germany, so you may be right about the
identity of the winder.
The earpieces use 50 (0.001 inch) or even 52 SWG. I have never dared to
ask what they use for the telecoils or earpieces in my behind-the-ear
