What are these speakers?

[Mattbedrock]

Just on a whim, I pulled out an old 2x12 guitar cabinet I hadn't used in some time for last nights gig. I was using my Ceriatone 1986x clone in 4 ohm mode, as I assumed these were two 8 ohm speakers. I was surprised at how nice and mellow this old cab sounded. I guess I'm having a senior moment, but for the life of me, I really can't remember what these speakers are. My dim memory is that they came out of a no name 4x12 cabinet that got destroyed on the road circa 1983 that I used with a small box Marshall 50 that I foolishly sold. I know I have told people that they are Eminence, but I'm not sure why.

Here's some pics:

The codes on the back of the magnet are:
79 4215
67 7348

If they are 1979 speakers, that wouldn't surprise me. The front picture shows they have aluminum dust caps with a black dot (a piece of felt?) in the center.

Any idea what these are or how I could find out?

Thanks in advance!

Sunn and Music Man used to use them, among others. I have a Super Reverb that came with the 10" version, sounds great!
