Thank you. Yes I only lost about a foot or two of the 40 gauge magnet wire on the coil so I'm still pretty close to what was originally there. Fingers crossed for the other coil. I agree I think the diaphagm is something other than metal. I'll take a closer look next time I'm in the shop and yes the metal reed is connected to the diaphragm and is what the magnetic field from the coils acts upon.
As for the one tube radio. I was able to locate one reference to it on the radiomuseum site which seemed to confirm the Century of Progress Worlds Fair connection that you initially identified. See: https://philcoradio.com/phorum/showthrea...#pid193628
