Vintage Ham Radio Speakers

This is an attempt to list the "matching" speaker for various vintage ham and communications receivers.
Often a receiver was advertised with several different speakers over its lifetime. And most hams used
homebrew speakers rather than the expensive matching one anyway!

This is definitely still a work in progress. I need more info!
