About 20 years ago I went to a tag sale at which a pair of speakers were being offered. Although I don't remember the exact wording that was used to describe them in the listing, it was not all that different than in the description cited by the OP. Turned out they were a pair of large vintage Tannoys, ca. 1960, which are highly sought after. I bought them for $20. After enjoying them for a while I eventually sold them for $1500. I suspect they would be worth several times that amount today.
