 I bought a Ridenour Ivorolon barrel with an R bore style. The literature states this barrel should be used with a large bore, low pitched mouthpiece. Does anyone know a good mouthpiece match for this barrel? The clarinet itself has a bore size of .577 measured three quarters of an inch into the clarinet at the end the barrel attaches; I don't know if this has any influence on the mouthpiece choice. The other end also measures .577 inch. 
 
This clarinet is for a student

 The tradational Chedeville-style mouthpieces should be nice with this barrel.  Also some of the Vandoren M pieces in the 13 series (esample: M13).  I think I used a similar barrel, and both my Gregory Smith Chedeville style mouthpiece and my Grabner K13 sounded great with it.  Tom also sells some nice hand-finished mouthpieces.  Check with him.

 On that auction web site, I just won a Ridenour Bb Clarinet ZMT36 mouthpiece made from a Zinner blank (what ever kind of blank that is).  The barrel is a Ridenour Ivorolon 67 mm with an R bore style. The clarinet is a 1952 model Edgware with a bore of .577. I hope it all work out.

 How does one tell the difference between Ivorolon tuning barrels.  Mine are unmarked, and I can't reach in far enough to measure their bores with my calipers.

 When I receive my R bore style, I will measure it. I emailed the seller yesterday as I have not yet received it, and it has been ten days. He was going to see if it was shipped so it may be some days before I receive it.

 Thank you. 
 
I've got two 62 mm Lyrique tuning barrels that came with my A clarinet.  Maybe later today, I'll try stuffing some modeling clay into them to make a mold that I can then measure.

 Here are the measurements I took of the two barrels that came with my Lyrique A clarinet. 
 
Barrel #1 (no commercial marking, but I added a piece of tape to write on): 
Length: 62-mm 
Upper bore 15.30 mm 
Lower bore 14.10-mm 
Upper socket depth 17.55-mm 
Lower socket depth 19.51-mm 
 
Barrel #2 (no commercial marking, but I added a piece of tape to write on): 
Length 62-mm 
Upper bore 14.10-mm 
Lower bore 14.30-mm 
Upper socket depth 17.25-mm 
Lower socket depth 19.50-mm 
 
Upper joint upper bore 14.8-mm 
Upper joint tenon length 17.95-mm 
 
Interestingly, the bottom sockets of the barrels are about 1.5-mm (0.06-in) longer than the upper joint's upper tenon --leaving a gap in the bore even when the barrel is pushed all the way in. 
 
Similarly, my mouthpiece tenons are about 17-mm long, leaving a similar 1.5-mm gap at the mouthpiece end. 
 
 
 
Interestingly,
