Russian made oval alto horn in Miraphone case, nice

An oval alto horn in Eb of unknown vintage (maybe '60's or '70s ?) in an older Miraphone case that fits the instrument great. The horn is nickel plate on brass. Very straight for an older instrument, the plating in in good shape as well. All valves and slides are free, it plays pretty well as far as alto horns go. About 24" tall with a bell 8 1/4" in diameter. Included is an unmarked mouthpiece that shows some wear but works fine. $500 firm cash on pickup, email to come take a look.
