Quote from: shmuelyosef on July 28, 2017, 01:36:38 PMThe bores are as-molded, toneholes are machined. At some point in the mid-60s, the open hole chimneys on the lower joint became pressed-in inserts.
On a different note as well regarding all these clarinets. Are the bores and/or toneholes machined? or are they just shipped as they come out of the molds?
I've compared my Normandy Special and Noblet 45 against an assortment of Normandy Reso-Tones and 1960s Vitos. I don't see the differences you're describing. The only thing of note I see relating to those keys is that for a short time in the early '60s, the E/B touchpiece got noticeably shorter, but reverted back after a few years.
