Chas, that is great info. I did not know that anyone made mica diaphragm horn drivers; that definitely is an improvement. I have a set of mic diaphragm "cans but o not have a band to fit them.
Worked on an RCA Frankenhorn with an Amplion driver and a wooden lamp base that definitely suffered from pot metal disease. Replaced the "carrier" with 2 spring loaded 8-32 screws with thumb nuts to adjust.
The prices that Mike described are rather high, but they are high on eBay also. I would be happy to just have a complete horn with base, but the days of picking up one even non-working for $25 are long gone. If the driver doesn't work, I can bury a 2.5" speaker and transformer into it if I can't fix it. I have several radios from 1921 -1924 including an A-K 10C a Westinghouse RC and a FADA 160, so I do need a horn to display these with.
