i have two... one - is in playing shape, looks pretty good when shined, i bought it to learn Eb for a reenactment group. high pitch. have not used it in a long time.
two - is a bit older, it was found in an old music store closet. it's apart, but i have all the pieces. needs a good clean, lots of dark tarnish.

i don't play Eb anymore and if i decide to, i'll got a newer instrument.

is there any value in these to anyone?

when i was playing #1, i had it chemically cleaned (i kept thinking spanish flu) i doubt the bacteria would still be there, but still, it gave me the creeps not knowing what lurked in the darkness... the valve corks/felts, etc replaced.
