Thanks Chas. I think you are correct, though I did not know what to call the diaphragm material. The horseshoe magnet is still relatively strong so I will give it a try before going the recharge route. I was able to get the second coil undone and had a similar experience to the first coil. I unwound about two feet of magnet wire, with about 3 breaks in roughly the same spot on the coil and then got continuity. Added in a new lead wire, reapplied the outer protective covering and also added one wrap of black electrical tape to hold it all together. Had to bridge the connection between the two coils but now I'm seeing 1821 ohms for both coils. I'll put it all back together next time, hook up to the Crosley Trirdyne and see what we have and if it survives when voltage is applied.

I also did a little more paint touch up to the horn where the pieces were glued back together. It will never look like new but this is about as good as I can do for it. I could repaint the entire horn and that might make it look better but I think this is the way I'll leave it. I did clean the horn with a mild detergent and then put on a paste wax to give it a little shine.
