Help with tweeter

[gagecalman]

Does anyone have any info on this type of Cerwin Vega tweeter?
I'm thinking up to 1980.
I don't see any model numbers.
I see a lot of CV tweeters with the exposed magnets and they always have numbers marked on them like C5G.
Thanks.

Those are Foster tweeters.

Those are Cerwin Vega HO5 tweeters, and they were indeed made by Foster.

Pre "D" series. Radio Shack also sold the same tweeter.
