Thought I'd give it a try, in case anyone here is interested in a nice cornet.
When I got this, the valve cluster was irreparably damaged. I replaced it with a cluster from a Reynolds cornet. The bore is identical and the Reynolds cluster uses all metal parts, so it will maintain the same playing characteristics. It also has silver balusters like the original Olds cluster. The overall fit was good, with a few modifications necessary to ensure that everything lines up. I made original-style braces for the two places where the dimensions changed. It's been lightly buffed and epoxy lacquered.
I'm not much of a cornet player, but I can tell the difference between this and my student-model cornets. It's a bit brighter than most of what I've played, with a nice dark core. It doesn't have the piercing tone of trumpets.
The slides work well. Originally, these didn't have an adjustable third valve slide, so I transferred the inners and outers from the Reynolds over, maintaining the crook from the Olds. I also moved the slide stop rod from the main tuning slide to the third valve, where it does more good.
It comes with an Olds 4 cornet mouthpiece, and a relatively new wood-sided cornet case.
