Anybody have a good line on the microphone/transmitter elements for the TS-13/TS-15 handsets that go with the BC-659 and BC-1000 handsets. The TS-9 elements (EE-8 Field telephone ) are too thick and too wide in diameter to work with the original handset body/cover.

I am rebuilding one TS-13 and one TS-15 handset. I have the correct ( and different from one another ) earpiece/ receiver elements

Also might help if anybody knows if the TS-13/TS-15 is a type F or type G handset.
