Cool euph! Didn't know Willson built bell-front models. Is there a model number on the mouthpiece receiver?
If you haven't already, you might try contacting Willi Kurath at mail@willson.ch with these photos, he's been very responsive and helpful in my experience.
Also if there is one, the serial number is usually on one of the valve casings.
Willson 2900 TA-1 Euphonium - Denis Wick 4AM

F.E. Olds Special Trombone (ca. 1941)
I actually received a response from Mr. Kurath yesterday stating that it must be an older instrument, about 30 years old. The serial number is 268xx. There isn’t a model number on the mouthpiece receiver.
It's been my impression that Europe had some models of horns similar to ours but with their own unique twists. The tubing wrap on this one might be an example. Willson is Swiss, and perhaps they have their own ideas.
An aside: in a conversation with Fred Marrich (Custom Music) years ago, he described the process they had gone through to bring the Hirsbrunner (Swiss) to market. In passing he mentioned that when he first visited the factory, he saw some relatively quirky horns. Of course, that's like talking about accents. I think Brooklyn folks have an accent, and they would say the same thing about me!
