This is from the original description of the flute purchased from a dealer in Poland:
Old German flute in e flat/440 HZ from 19th century (about 1860-1890) made in black cocuswood with 6 keys and tuning slide, length about 580mm.
The flute was repaired and fully reconditioned, with new synthetic pads, cleared, etc, in a professional workshop by Grzegorz Tomaszewicz - gtmusicalinstruments.com
The instrument was originally tuned to A 432 Hz., now plays in 440 Hz
My additional comments:
This flute is in great condition, with tight seals on keys. It has small finger holes, and a clear mellow tone. The head is fully lined. Since the flute is pitched to E flat, the distance between holes is smaller, so requires less finger stretch to play.
