OK, in fact I have read the archives about mouthpieces that are too fat for barrel sockets. This is a different problem. It's not too tight a fit, it just doesn't go all the way into the barrel socket. Five clarinets tried, and only one barrel admits this mouthpiece fully. Even then, there's half a mm still to go.
So I have compared this "new" mouthpiece with other, identical blanks. I can't see any difference in the tenon length, cork dimensions, etc. It is a c. 1950s-1960s Chedeville QS number 10. The mouthpiece slides into different barrels without undue resistance but never reaches fully into the socket.
Any ideas what might be going wrong? Just a manufacturing anomaly? I appreciate any responses. Thanks.
Bill.

Maybe there's a "ridge" at the very top of the mp tenon...above the cork

Thanks Bob. I managed to get it into an old Buffet that I hadn't tried before (and played some Poulenc, roaring my way through some ppp passages just because I was tired of of sustaining such a delicate approach ... one needs full support in soft passages - kind of hard to work out for very long).
Yeah, I wonder whether there is a ridge at the top - maybe the cork is uneven. Good suggestion.
Bill.

I've had one that behaved this way. (a cheap plastic thing, unlike yours)
The reason was that the barrel's socket wasn't reamed out right into the corner (making a sharp 90° angle there) but there was a 45° bevel between wall and bottom of the socket. Now the mouthpiece's tenon had a very sharp edge which would sit on the socket's bevel upon assembling.
I dulled the mpc's tenon edge and voilà, in it went. (it was still a cheap plastic thing, and its merits weren't on the musical side but rather to offer some insights into the mechanics of clarinet assembly)

I had a Chedeville , circa 1952, and a Selmer, circa 1947. They fit together well. Years later I did grind, about 0.1mm, some Vandorens and Woodwinds for Buffets and Leblancs.

Thanks, Steve. In taking the pictures I think I realized what the problem might be. The cork seems to rest too high up ... or something.
The "problem" mouthpiece is the one marked on the photos. ROAD TRIP!!!

I would suggest the mouthpiece is fine the way it is. The very end is supposed to butt up against the inside of the barrel. If there is a gap on the outside between the barrel and mouthpiece this shouldn't be a problem. If you want you could fill this gap with a washer to stabilize the mouthpiece from rocking. The opposite situation can occur when people think the mouthpiece is hitting bottom when in fact it is just the external parts of the mouthpiece and barrel touching. This creates a gap inside the bore.

Bill,
Is it just my imagination, or is the tenon longer on that one? I know you said there was no difference but it kinda looks longer in the pictures.

Thanks! I ended up just taking off the cork. It seemed to me that the cork was run up too close to the shoulder of the mouthpiece (and table). I hadn't noticed this (for some reason) before taking the pictures!!!
With the cork removed and tape in its place, it fits fine.
Bill.

Bill,
Looking at those pics I couldn't get past the feeling that someone was staring at me .....
You should have just trimmed some cork off with a razor blade instead of just removing it all.
But Susie has something - the tenon lengths looks longer on the "faced" mpc on the right. Makes you wonder if the shorter one has a gap inside.
I've also have had mpcs with cork going all the way up, when you insert it the cork tends to 'ride up' and blocks the mpc from from going all the way in and leaves a little gap between the mpc and barrel.
