Thanks a lot to everyone who replied to my post.
I finished the restoration, with one remaining problem: tenons do not fit into corresponding sockets due to wood bunding. The middle tenon can be fit with small effort, but the barrel and bell are no go.
Both bell and barrel from my clarinet fit fine, so I think that the original bell and barrel need to be reamed.
BTW, it sounds nice with barrel and bell from my clarinet, relatively good tuning too.
However, it was a project I underestimated in difficulty and time needed.
In a shop, it could have been done in a day or less (I think...)
