I have a LeBlanc Bass Clarinet that's been in my family for quite a while. The only information I have on it is a serial number (6583) and a marking at the neck connector (28). Can anyone tell me what model this is? I just dropped it off today to have it polished & get new pads, and the clerk was very impressed. I called LeBlanc, but they've just been bought by Selmer, so there are no older records available to me.

Please help!!
