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!

Here are some questions I have:

Q: National HRO-60TS speaker vs. NC-183DTS speaker - is there any difference between these two speakers?
A: Probably not - see below.
Q: National HRO-50TS speaker vs. NC-183TS speaker - is there any difference between these two speakers?
A: NO - Barry KD5VC has a new in the box speaker - the box is marked "BM-469 Gray" and "FOR NC-183 or HRO-50"
