This is Peter Ponzol and I want to correct some information on your Keilwerth web site. The Modell Peter Ponzol was made from 1986 until I left the company in 1993, not for three years as your site states. When I joined Keilwerth as consultant and designer in 1985 (after having worked for Buffet for three years), I convinced Keilwerth to stop making stencil instruments and to build a reputation for the Keilwerth name by making only Keilwerth instruments. My model was the top of the line and was the last to have real rolled tone holes. These instruments are much sought after in Europe. My model had a different neck which was chosen by me to match each saxophone, and I personally went in the factory every week to test every Ponzol saxophone. It was on my model that the following were developed: adjustable palm keys, right hand F arm bridge with adjusting screw and the G# lever which prevents sticking of the G# key. Also the few Keilwerh copper horns made were all Ponzol models.

By the way, since Graslitz was in the Sudentland technically all Keilwerth horns were made in Germany. This area belonged to Germany until the end of World War 2 when Keilwerth moved to Nauheim, W. Germany along with the Winter and Schreiber families.
