I've been wondering for a while now how old my flute is exactly. The serial number is 129323 and I've had it for about 4-5 years. It is still my first flute, and I'm wondering if anybody could tell me anything about the flute, and something about how old it might possibly be.
Any help at all would be greatly apreciated.

The Buescher name was indeed bought by Selmer I think in the early 1960s. Most likely, the Buescher Aristocrat flute is the same as a Bundy or possibly a Selmer Signet. Serial number lists for the Buescher flutes do not seem to be readily available anywhere on the web, but it probably dates to sometime in the 60s or 70s.
