It’s an original Siemens Halske SH. III 11-cylinder  geared rotary. 200hp

Wow, cant wait to see it fly and to hear the sound. Thanks for sharing.

Wow, that's Baumers skin!

@J5_Hellbender - Pfalz D.VIII was contemporary of Fokker Dr.I, used in spring 1918. (Also, it had more props; that 4-blade prop was in fact two conventional props mounted orthogonally.)

AW 11608  Pfalz D.VII / VIII

The Pfalz DVII /VIII biplanes evolved from the Dr.I.   First flown in December 1917,

it used the same 160 hp. Siemens-Halske engine. Performance was excellent especially

in climb provided the Siemens-Halske engine was not over heating or having other

teething problems. As a result, the DVII went into small scale production for front line

evaluation. The DVIII went into production Feburary 1918, reaching the front by April.

However these were not released for combat duty until June of that year. Reports indicate

that it was equal to the SSW DIV in speed and climb but inferior in maneuverability.

I was wondering why Mikael staes 200hp but every other source is 160. It was actually a Maximum of 240 hp

 

From Wiki: 

 

• Power output: 120 kW (160 hp) [up to a maximum of 180 kW (240 hp)]^[2]

Video update. Also, Wiki states contra-rotary. I guess I don't understand looking at the video, because both the prop and block are rotating in the same direction.

Interesting starting system. It looks like they position the bottom cylinder to (I imagine) a few degrees after TDC, then a hand-cranked generator builds a charge used to energise the spark plug.  Does anyone know what this technique is called or anything else about it?

Could be this like inside the DVII

The crankshaft is rotating in the opposite direction compared to the prop and block. Therefor the engine runs at a lower rpm with the same number of ignitions so to speak. And therefor a fourbladed prop. Or as you or someone mentioned, two props on top of each other. :-)
