Olds Star Moutpiece

Post by guywiththeblacktrombone » Wed Oct 09, 2019 8:04 am

Does anyone know what the star after the mouthpiece model indicates? I have a very old Olds 12C* and wanted to know if it was different than their 12C.

Thanks!

I know a 1* is definitely different from a 1, so I would give a provisional "yes". How it's different I could not say. Nothing in any of the Olds literature I have about the star mouthpiece models.

Which style of blank is it?

It is the first later style.
They seem to play very close to one another.

There is apparently nothing straightforward about the Olds mouthpiece numbering system.

I was given several Olds mouthpieces by a retired trombonist, including some with an engraved "star" after the number. They all have the old-fashioned Olds "tulip" blank. The "star" versions are indeed slightly different. Here is what I have measured:

Model: Cup I.D. | Throat
3C: 24.25mm / 0.955" | 5.85mm / 0.230"
3 (old): ~24.20mm / 0.953" | 6.15mm / 0.242"
3 (newer): ~24.25mm / 0.955" | 6.15mm / 0.242"
3*: ~24.25mm / 0.955" | 6.25mm / 0.246" [Slightly larger throat than standard Olds 3]
4: ~24.0mm / 0.990" | 6.15mm / 0.242"
12C: 24.50mm / 0.965" | 5.85mm / 0.230"
1: 24.50mm / 0.965" | 6.35mm / 0.250"
1*: 24.50mm / 0.965" | 6.25mm / 0.246" [Slightly smaller throat than standard Olds 1]
