Re: Low B-C linkage adustment

It can be fitted to most oboes where the low B and C keys share the same central pillar instead of being mounted on separate sets of pillars - some older Marigaux and Buffet oboes have these keys mounted separately. It can still be done, but the linkage arm will be long or a bar may have to be soldered to the part of the C key that links it to close the Eb pad cup if there's no room at the lower end of the C key rod or barrel between the lower pillar and the C key cup arm. If the C key is mounted between point screws, then these have to be an excellent fit for the B-C link to be reliable as any slop in the fitting of the C key will make the adjustment difficult or unreliable.

Howarth oboes often have the low B-C linkage arm mounted in such a way that it can be fully disengaged by backing off the adjusting screw - older Howarths that have the low B-C link have it mounted with some room for minor adjustment, but it can't be completely disengaged to allow the C key to open fully should you want to use the low B key independently for some altissimo notes or as a resonance key for some upper register notes.
