Hi, I’ve got a single vintage horn driver but there is no clue to know who made it. Need your help to identify then maybe I will have a chance to find another one to make a pair. Thank you for any clue or comments.
Please help to identify vintage compression driver

I'm not 100% on it.
But, i think it's a Western Electric 720A/722A, or perhaps some variation of the 722A made for GSA contract.

Thank you. Good news: it is highly likely that it is a driver made by Western Electric. Bad news is that it has a round base, not a rectangular base like a WE 722a.
@bowtie427ss and Pio1980: what is a GSA contract?

Likely to be a PA class driver, not everything that came from WE was "Holy Grail".

722A has the round base, or at least had it for part of it's production. Some also had a rounded metal "can" covering the rear of the magnet structure.
Don't forget, Altec continued production of these drivers for some time. Altec was also awarded many GSA contracts well into the 70's. Some contracted products would almost certainly have specific changes or revisions per the customer's specs.

Thank you. Not so bad these old drivers. I just play around with some PA horns from Altec. The result is absolutely astonishing . Their response range is within 300 to 6000 Hz, not so impressive. But the touch that they add to my system is so so nice. Especially on percussion.
