Question about gooseneck
I acquired an 1959 Olds keyed trombone, the gooseneck and slide coupler have been removed form the instrument, the gooseneck has a strange taper to it similar to the neck on a rifle casing. Has anyone seen this before?

Question about gooseneck
I'm really not sure what you mean. Pictures would be useful but you can't post them here directly because this forum's storage is full, you can only post a link to them like on Dropbox or another site.

Question about gooseneck
Do you mean it looks something like this?
If that's the case, what you have is a raw part that hasn't been trimmed. The end is shrunk down so that the tube can be drawn over a mandrel, then that end is cut off before it is installed.

Yes that is exactually what it looks like. so I just need to calculate how much of the pipe I need for the slide to fit correctly.

Question about gooseneck
Sounds like the original was damaged beyond repair & someone tried to make a new one.
Measure the inside diameter of the slide receiver and also the tuning slide receiver & match to the outer diameter of the new pipe.
Might match up to the needed length, but I wouldn't bet on it, you'll have to fudge somewhere.

The receiver would connect to the bell brace, so the neckpipe length should be the exact amount to span the distance between receiver and small tuning slide tube ferrule, plus the amount of insertion on both ends. Are you planning on assembling this yourself?

Question about gooseneck
If I understand you correctly, what has been replaced is the tube between the receiver and the valve cluster. If that's the case, you're looking at the most fragile and most frequently destroyed part of an Olds valve trombone. The tube takes a dog-leg bend, and needs to end roughly 3/4 of an inch below the point where it exits the valve casing. Do you have a bent tube there, or did someone put in a straight tube? Can you provide pictures?

I am replacing is the one that comes from the bottom of the tuning slide to the connection with the slide.

That's a pretty standard item. I'm pretty sure one from an Ambassador would have the same dimensions. I could measure against an Olds valve trombone bell and see if they're similar. PM me if you're interested in an Ambassador replacement neckpipe and receiver. I've got a few of them.
