Vintage 10'' Perm-O-Flux guitar amplifier/amp loudspeaker

Vintage 10 inch diameter speaker. This speaker is marked "25812-4", "719" and "3 39" in paint on the metal speaker frame. It is also stamped "P2231" on the backside of the speaker cone. We don't know much about this speaker, but we've been told that this speaker is probably made by Perm-O-Flux (because of the 258 in the first code) but is might also be Carbonneau ("719") and that both makers produced guitar and amplifier speakers.

We've hooked this speaker to a VCR as the sound source and it works
