The Hans Hoyer model G10 is styled after the original instruments by Carl Geyer, who immigrated to the United States in 1903. The well balanced design is very similar to the original of the 1950’s with rich tone colors and similar resistance. It is handmade by B&S/Buffet in Germany.
Careful attention is given to the positioning of the braces as well as on the ergonomic arrangement of the valve and thumb levers.
Loosely translated from German, the above statement means "the thumb lever is not ergonomic", but I/Steve make an adjustment so it fits most human hands.
