Acousticion super tweeter #1202s, what do I have here?

I won these tweeters in a goodwill auction, $20.00 with shipping for the pair.
I can't find any info on them, have been scouring google images for tweeters that look the same, hoping to maybe find the OEM as well.
Anyone have any info?
They look like they've been kicking around in someones junk drawer for 20 years, but they seem to be decent quality, weight just shy of 3 pounds each and sound good. No critical listening yet just sitting on top of open back speaker boxes supplementing the high end on some Phillips 1256/M8s.
