From appendix 6: There was an aircraft of those known as pioneers in the year 1909 that was based on the Bleriot XI. An English airplane with the variant of having two horizontal stabilizers on the tail. It was the Windham monoplane.

-It was able to use two types of engines of four cylinders in V and 20/25 hp both.

-One was the Jap (see main text) with a V angle of 90^o or the other engine that was the Advance with a smaller V angle.

-But here we show this amplification for the propeller that was used by this aircraft of a very curious design.

From Appendix 7: Another installation, different from the one in the main text, of a four-cylinder Advance V engine that gave 20/25 hp.
