At Oshkosh 2007 there was an old three-cylinder, inverted Y engine that could have been mistaken for a Kinner or a Poyer if it were not for the casting marks on the central crankcase.

-Interestingly the engine is mentioned as a "Connor" when in the central block is clearly written "CONNER MOTOR Co.".

-In addition the place of manufacture is in "Chas City Iowa" when the writing mentions "Charles City in Iowa". That could be possible because it may be a contraction or AKA the city name.

-The lower part has an accessory that may be an oil cooler with fins.

-Modernly it has the shape of a vacuum pump but it would be the worst place to install it.

-Some screws are missing on the crankcase and the front bearing cover. Possibly on the rear side it is more mutilated.
