Please Complete My Education!

So I came across this advert on ebay. I'm not thinking of buying but had never heard of a Stomvi trombone so opened the ad up. Interesting looking horn with some unique angles on construction but this has left me curious. I expected to find a chinese clone or something but this is clearly an original horn. Probably German made I would guess. Someone on the forum is going to complete my education and tell me all about Stomvi I am sure?....

I think they are Spanish. The couple I've played have been really excellent.

They are reportedly really good.

Diggin' the built in resistance balancer on the bell flange. Very cool looking!

Was that how Minick used to brace some of the horns he did? It does look really slick, I wonder if there's a reason I don't see that type of bracing elsewhere.

They are a Spanish company with great trumpets. Would expect their reputation to carry on to other instruments.

I believe that is a slip collar for the removable bell. They use a very different design compared to pretty much everyone else. There is a screw ring at the start of the stem on the Titan horns and they call it the "one screw design."

They are super nice also.

That's pretty cool. I imagine the bracing like that has a huge impact on the response. Very cool that it has another different and equally important function.

The valve design also looks open. Large design.

I used to play a Courtois bass that had an axial screw for the removable bell like this, but then it was a conventional screw on the bell brace. This brings it to another level and makes so much sense! I wonder if the bell just sits more or less loosely in the sleeve, or if it friction fits in there?

You mean, whether or not it buzzes like crazy?

The screw pulls the bell back into the tapered sleeve, so 'how firm' would have to depend on 'how screwed', but given the surface area involved I'd have thought a certain level would be required to avoid nodal percussion.

Here's a picture from the Stomvi website:

That sounds like one of the models that used the Vibrabell system from Rene Hagmann.
