PA SPEAKERS 8" WITH MATCHING TRANSFORMER CEILING MOUNT | eBay

Stamped 8", an altec model?

Maybe others used the same green?

Have seen Heppner that looked like that.

I had some Setchell Carlson speakers that looked like that. They were plated, and not painted, Though. I don't think I have them anymore, but it seems like they didn't have any EIA codes.
