    I think they stopped doing this now, but as recent as a few years ago Conn 88H trombones were shipping with several removable leadpipes, and one of them had a remington taper receiver in it.

    iiipopes. I knew that the CONN 24I/25I were not the same as the 88H Remington shank. So I will agree it is not Remington. Everything else that I said is true.

    A Euro medium shank will bottom out and not engage in the receiver without being shaved. If 1/4" or so is removed, it will work nicely. The Conn tenor shank adapter that came with the Connstellation worked nicely in the Besson New Standard, but the Besson adapter that came with the older medium shank New Standards would wobble in the Conn. I have played with this adaptation (pun intended) since 1965 when I played my first Connstellation (still have one).

    I just deleted a post because it was getting more pointed than I'm comfortable with. Let's all be respectful, and avoid sarcasm. Thanks!

The middle size, which is called the Euro shank, fits the old Bessons (pre 1974) and most Willsons. And the large, bass-trombone-size shank fits most modern euphoniums.

    Speaking a little roughly, if you measure the small end of the mouthpiece, you'll find this:

    Small, tenor trombone-size shank: 7/16" or 11mm
    Large, bass trombone-size shank: 1/2" or 12mm

    The medium (European) shank measures about halfway between the other 2, or 15/32" or 11.5mm

    I checked with a AAA battery, and the diameter is very close to the end of the small shank mouthpiece. The AAA battery ALMOST fits inside the end of the large shank.
    The length of the shank of a mouthpiece can vary within a given taper size. Also, some mouthpieces have had the end shortened for various reasons (damage, "gap" adjustment etc.) This matters when measuring the end of the shank to determine mouthpiece size because the longer the shank, the smaller the diameter at the end and obviously the shorter the shank, the wider the end diameter due to it being tapered.

    What actually matters is the inside diameter of the receiver which the mouthpiece shank goes into.
    Kelly Mouthpieces has a nice chart giving these dimensions:

    https://www.kellymouthpieces.com/shanks/index.asp

    After reading some of the discussions on mouthpiece to lead-pipe "gap" as well as other threads on poorly fitting shanks, I think the problem some people are encountering is the end of the mouthpiece shank bottoming out against the lead-pipe inside the receiver such that the taper of the shank does not quite fully seat into the taper of the receiver. Filing off a bit of the end of the shank would fix this. Note that unlike an adjustable gap receiver, this is simply allowing the mouthpiece to fully seat into the receiver. An adjustable gap allows for tuning of the tubing prior to the valve section. Most people will never encounter a problem in this. But, in the world of repair of student/school instruments, the receiver and lead-pipes can take a beating in the field and may need to be rebuilt/replaced. The slight variations in mouthpiece shank length and tuning problems can become evident if a receiver is set too far in or out when it is replaced.

    Since this has been revived, I have a weird question.

    I tried a King 2280 years ago and even though it's marked as a "large shank" receiver, none of my mouthpieces seemed to fit correctly. It wasn't completely incorrect, but just didn't "fit" and snug into place. I used Schilke and Wick mp's, but I don't think I tried a large shank Bach. Then more recently I tried a Yamaha Bass Trombone and had the same issue. This one came with a Schilke 59 that I tried in my Euph and noticed it stuck out farther than in the Bass Trombone.

    Is there a specific "Bass Trombone" shank out there, different from a Large Shank?
