Sorry man, this website is for saxes only, you won't find many people with flute info. I do own a newer Gemeinhart flute, they're nice flutes aren't they? lol sorry i cant help ya

Just because this is a saxophone site does not mean we don't try to help each other out with other instruments. Have you tried calling a musical instrument store? Sometimes they have books with serial number charts that can help determine the age. I called mine, though, and they don't have a chart for Gemeinhardt. However, they asked me to call back about 10:00 central time (which I can't do today because of a meeting). You may try. Schmitt Music in Bloomington MN, ask for Doug. 1-800-767-3434 I also visited the website for Gemeinhardt, and didn't find any help there. Sorry
