In Breguet Challenge #424 the Mercedes engined version was pictured and identified, but much text was written there about this Siemens Halske Sh I rotary engine version.
Probably the rules must be (again) more specified as what defines a machine. Makes a new Mark or engine or substitution of a four-bladed airscrew for a two-blader another machine. In short when is the above rule violated?
The Siemens Halske Sh I was an interesting rotary engine. In German language it was known as a 'Gegenläufer', I know what they mean in German but I cannot translate the technical terms in English though.

I think the best English translation for 'Gegenläufer' in this case would be contrarotation. I'm assuming this is one of the rotary engines where the propellor rotates in the opposite direction to the engine to reduce the torque effect.
