I had the same experience about 30 years ago. A very old man (more than 80) had a used book store with 5 meters high shelves and stacks and piles and heaps everywhere. I came in and asked "do you have the works of Antiphon, by any chance? The bilingual version?" "He think for a moment, "ah, do you mean the 1923 translation? I must have it somewhere up there..." And he went up a ladder, rummaged on some shelves, and came back with the old, uncut book, in the battered original edition. I've bought many, many books there for a while, particularly the rare (and expensive when new) "Guillaume Budé" books in their original, paper-cover, uncut editions (https://www.lesbelleslettres.com/les-budes https://www.lesbelleslettres.com/les-budes). Some very sad day, the guy died and the magic store closed forever.
