Hello all! I've been using this plastic school model Bundy for quite a while now, and recently I'm looking into buying a new instrument. I've been trying to find a date on when it was manufactured, but it seems as though there's not a lot of information on Bundy manufacturing dates for bass clarinets. The serial number on mine is 1305138. Besides the date, what do plastic Bundy's go for on the market these days? I don't even have a basis on how much I bought it for because it was gifted to me. Besides some wear on the nickel plating on the keys, I have replaced most of the pads, and it's in great working condition.
