From a previous post:
I have a Selmer 10G with a +/- 66mm barrel. The horn plays sharp in the left hand (upper joint) and progressively flatter as one descends in the right hand. Such a disparity! On the Fobes site are listed barrels for older Selmers that are claimed to lower the upper clarion??? BTW: the 10G barrel and upper joint bores are both rubber sleeved. Any advise re barrels would be appreciated.
Too, would fraising several lower stack tone hole be practical? Then, how to sharpen long B (middle staff line)? Hole in bell? Shorter bell?

How are you tuning? If the left hand notes are sharp what happens if you pull out at the barrel until open G is in tune?
I don't know much about Selmers, but I didn't think they had a rubber lined upper joint. I though it was only the barrel. Chris P will probably chime in but it might be possible someone re-bored this clarinet and it caused more problems than it solved.
A hole in the bell can definitely solve a sharp clarion B, but if it gets to the point where this instrument needs major tuning work to play in tune it may not be the right horn for you.

Strange, I have owned a 10G that tuned actually very well. But mine didn't have rubber sleeving. May be the sleeving is not original on yours?

My 10Gs tune very evenly. My Bb barrel is 66mm and my A barrel is 65mm - both are the original equipment. The barrels are lined (not the clarinets). But my experience with my clarine and others my students have bought suggests that something has happened (or was done) to yours to cause the tuning problem you've described.

I never saw a Selmer Paris clarinet with a rubber lining. You didn't indicate if both registers were the same.
A longer barrel will lower the upper joint notes more than the lower joint notes, but it isn't a practical fix if the whole instrument becomes flat.
Fraising will mostly raise the chalameau notes. I've used it mostly on the upper joint.
I think that the bore of your barrel and upper joint may be the issue.

I've only seen ebonite lined barrels on 10Gs but never the top joint bore. It ought to be an option on all new wooden pro level clarinets just as it is for oboes - the only clarinets I know of with lined top joint bores are Yamaha 450 Duet+ models.
Do you know if the ebonite sleeve is factory fitted or was done afterwards by an independent repairer?

Chris P,
An upper joint bore lining actually is now an option on all Selmer Paris pro level clarinets, but it isn't necessarily rubber, it's a "new patented resin" made with "molecules derived from biomass." For all I know that may be essentially rubber ... They call it "EVOLUTION★."

However, this is a recent development, and I think OP's clarinet is almost certainly an aftermarket modification.

Maybe the sleeve in the upper joint wasn't reamed out to the proper spec.

Bit off topic, but if you go to the link provided by jcm499 there’s a very interesting graph showing the tuning variation in the unlined Privilege range as compared to the lined. What surprised me was the huge variation #/b across the range (>15% sharp/flat in many cases). Also surprised Selmer would publish that.

A different mouthpiece may fix the issue. The mouthpiece affects the tuning of the closest notes more than the long notes.

To my knowledge, the 10G A clarinet had a barrel with a hard-rubber lining. The 10G Bb did not. That is true on my pair of 10Gs. They tune very well, so your situation intrigues me.

10G Bbs also had ebonite lined barrels - not sure exactly when Selmer introduced that on them, but at some point in time (probably during the '90s) they definitely did.

Both of my (original equipment) barrels - A and Bb - have linings.

They were a feature from the beginning. Hans Moennig had been lining stock Buffet barrels and it was one of the things Gigliotti had Selmer copy when the 10G was designed.
