This is a long shot, but what the heck.

I tried a Rath R3 a couple years ago when I visited Mick's shop in England. I fell in love with it. It was easily the most responsive .525 straight horn I have ever played.

I have been wanting one on and off ever since. If any one here has one that they are looking to sell, let me know.

The one I tried had a nickle bell, and a yellow brass slide.
