The aircraft will be powered by a Siemens Sh13 engine (The five cylinder cousin of the Sh14) which in turn requires Bosch JF5 magnetos. These magnetos were also used on smaller Warner radial engines in the USA where they were known as "American Bosch JF5".
Dieter would be very grateful for any information that might help track down some magnetos for his project. If you can help, please contact Hermann Diebold who will pass it on.
