Got you beat. My oldest horn is a c. 1920 curved soprano, nominally a Wurlitzer (really made by Beuscher).
Or rather, that's my oldest playable horn. I have a Millereau double-octave-key soprano from 1900 or 1901 that I've never even tried to get into playable condition. It's just a cool object.
Very cool! I'm not a collector or by any means a musician, but I obviously got that alto to play (I got it in playable shape, but it has its warts and all ... but I love it, though I don't play these days).
Anyway, my old Lenco rekkid player surely qualifies, too. No idea from what time it dates, but it looks more or less like this one below, but doesn't have a suspender for the cover (which no doubt was added later), and it doesn't have that wooden frame at the bottom, either:
oh, and the lid/cover of mine is in much better shape, no holes or tears or anything!
