I am trying to figure out who might have made this mouthpipe and what it fits. The only marking is an ( S ) on the front face of the rim.

I don't know what the problem is, but if I copy your URL into a new tab I can see your pictures. I can't see them within the post.

Incidentally, the usual term for this part is "leadpipe""

On many leadpipes an S indicates a small shank mouthpiece.

It looks like a Shires leadpipe collar, but a Shires leadpipe should have a number (1, 1.5, 2, 2.5, or 3) and possibly some modifying letters indicating material (G for gold brass, N for nickel silver, SS for sterling silver, no mark for yellow brass), length (S for Short and L for Long), and bore (unmarked means large bore tenor). Early in Shires history, their "standard" parts didn't have modifying indicators on them, and that holds true for leadpipes--the large bore tenor pipes are unmarked.

So my best guess based on the provided information is that it's an early 2S leadpipe in yellow brass for a large-bore tenor, and the "2" was suppressed because it was Shires' standard leadpipe.

To check this, measure the distal diameter of the pipe with a good set of calipers. If it's for a large-bore it will measure a bit less than 0.546", and check to see if a large-shank Morse taper mouthpiece fits properly.

That's a Conn collar. The S indicates "standard". There was also the R (which had a Remington receiver) and M as the 3 pipes provided with the Conn 88H.

Thanks Guys. It is definitely a large shank receiver. I appreciate the feedback and now know what to check it against.

As Matthew said it is standard Conn leadpipe for 8H/88H, with added collar for use in SL4747 and SL4762 handslides.

Thanks, Matt. How can you distinguish between Conn and Shires collars from photos? The knurling looks very similar.

Shires have a thinner... end part of the leadpipe. They also have finer knurling.

Thanks, Aidan.
