This post was obviously for me and a very small, close circle of friends.
We worked for many years at a wonderful, confusing, infuriating, but awesome second hand music store that specialized in obscure instruments. Banjo-ukes lined a wall, surrounded by beautiful vintage (and sometimes koa) ukes. Next to them were the ouds, balalaikas, bouzoukis; then the hurdy gurdys, Hardanger fiddle (singular), arch-top mandolins (edit: and a few 'bowl back' mandos, though i can't think of their proper name), and near-turn-century Gibson/Martin guitars.
Of course I was the woodwind/brass guy, so I got to see even weirder stuff. But that is a tale for another time
