Olds Super leadpipe replacement?

Mine is from L.A. I had to have the inners replaced due to way too much chrome loss, and the leadpipe looked pretty bad at the time. It's also the "Olds taper" I believe since Morse taper mps wobble a bit. Is there an option out there for the slide dimensions of this horn?

It all depends on what kind of tubes were used as replacements. If the new upper inner is a modern .485" tube, a modern .485" leadpipe should work fine.
That said, this is probably something you should discuss with whoever did the tube replacement for you. Find out what the ID of the upper inner is at the leadpipe end; then you can ask vendors what the OD of their leadpipes are at the receiver end.
There aren't that many options for .485" leadpipes. I know Shires makes some. Brad Close/Brass Ark doesn't list a .485", nor does M/K Drawing. Modifying a .481" pipe might be an option - once again, that's something to discuss with your tech.

Thanks. "Modern" round tubes were used as replacements, not the historically correct/original-type octagons.

Good to know. I will be asking a nearby tech well versed in trombone anatomy about the project. Thanks.

Good idea. Since Olds had the smaller receiver type, a .485 leadpipe with a standard small shank receiver might not fit all the way in. The outer diameter at the receiver end is normally more than .485.

The inner slide tube could be reamed out to accept the new pipe, as well as the new leadpipe can be thinned at the very top to allow it to fit. A selective combination of both should get you a good result.

I worked on a super a year or two ago that had the leadpipe out maybe 3/16 from the end of the inner tube/mouthpiece receiver edge with a thin brass collar around it (everything was soldered in). It looked factory and was elegant, and might be a solution to give more wiggle room for the leadpipe for a standard shank to seat?
