Who is Walter Höffle.
As a former manager of the truck division of Mercedes Benz, Walter managed a design department. In that time his hobby was modelling and he has build an exact copy on scale of a Mercedes truck. During his work he has learned to make first a drawing of his ideas and then make them. When he was 55 years old, he retired and got the idea to chose home organ building as a hobby.
Walter wrote also a construction plan about a 20 key MIDI driven crank organ. This organ has 5 registers: stopped, stopped vribrato, wood picolo, violin and quint. This book is only in German available and can be obtained at: Hobbycrankorgan
