How to Check Altus Serial Numbers for Year of Manufacture?

[flutego12]

Dear fellow flute enthusiasts

Does anyone know how one goes about checking Year of Manufacture for 2nd hand flutes?

Muramatsu America & Yamaha USA are amazing in their support on this.
Can somebody know how one can check for Altusses and Miyazawas?
