Pictured are three Lätzsch Modell Kuhn trombones. Left to right. Mid 50's Weite 2, early 60's Weite 4, and mid 50's Weite 4. The one on the right I bought already in Australia in the mid 1980's. It was languishing in a store room at a school in Sydney. Apparently having been bequeathed to the school by a German emigré trombonist who had formerly taught there. I bought it for a very reasonable price and was probably the only person who knew that this was a top-level professional instrument.
Explanation about the description Weite. It means "width" and refers to the bore size of the trombones. The Lätzsch German trombones were/are produced with 5 different (dual) bore sizes. Same design but with increasing bore sizes. Weite 1 is the narrowest and Weite 5 is the widest. Generally, the orchestral 1st trombone would play on a Weite 2 instrument (bore 12.4/12.9 mm). The second on Weite 3 or 4, and the bass on Weite 5. It is a logical system. In Vienna however, for years the whole section played on Weite 4 instruments. Different tradition. Nowadays this German style trombone is not found in the Vienna Phil, and is also out of favour in German orchestras as well, although many bass trombonists in Germany still play the Lätzsch German style bass (often the Cieslik model)
These below are the Lätzsch bore sizes. Other builders use their own preferred measurements. Markus Leuchter offer three bore sizes, for instance, and Helmut Voigt four.
Weite 1 11.9/12.4 mm (.468/.488")
Weite 2 12.4/12.9 mm (.488/.507")
Weite 3 12.9/13.4 mm (.507/.527")
Weite 4 13.4/13.9 mm (.527/.547")
Weite 5 13.9/14.4 mm (.547/.567")
So we have smaller bore sizes than American-style trombones, but wider bell throats and diameters (23cm). Also snake decorations on the bell and slide bows, and the nickel silver rim (1cm on Lätzsch trombones). All three and in Goldbrass. The middle trombone has nickel outer slides (not lightweight...), slide crook also gold brass on all three. All three have the long water key... a favourite option of mine. Traditionally the German slide is longer than a standard American trombone. You can see from my last post with the Holton that the overall length is shorter on the German trombone. Shorter and wider bell section accounts for this.
