For Porsche, the original production series of 25 917s could not satisfy demand.

It was subsequently decided that the production series should have a 250hp diesel engine.

Basic passenger version, five aircraft were built, one prototype and four production series.

About 9000 pistols were made in four production series.

In October that year a first production series of ten is ordered.

In 1961 the production series was started, the run lasting until 1963.

Construction of the production series commenced in 1905 and continued until 1919.

The production series is somewhat different in design and performance.

No prototype preceded the production series of 12 aircraft completed in 1937.

The "Greeny" model is available for purchase from the production series.
