Need help identifying these speakers purchased in 1992

Pics are not showing for me. Have you made them public?

Oops, here's the public link:

The mystery is, why? 

If they work, then its really a mystery.

If they don't, then its either a driver or a crossover. And either way it doesn't matter who made the speakers, you'll just replace the bad driver, caps, terminals, etc. All of which can be done without knowing anything about the manufacturer or model of the speaker.

So.. why?

They still sound amazing but I’m selling them as part of downsizing. 

I'm not sure you'll find much of a market for 30 year old brand-less, bookshelf speakers.  I suppose it could be helpful to find out who the manufacturer was to list on a Goodwill donation receipt.  I think the tax deduction may be the best bet.  Otherwise I'd gift them to a friend or relative which is good karma.
