Rare aeronautical engine presented by this company at the Fair of Samples (Fiera Campionaria) of Milan, in the year 1934.

"Singular De-Wrachien engine" (PiP=LBC)

-It seems to have two toroidal bodies by the way the two spark plugs appear on one side.

-There is some similarity with another very rare engine shown in the UFE chapter with reference number 137. An engine of four bodies. (Wankel was not yet known).

-We continue investigating.
