02/28/2008. Remarks by Jack McKillop: "Orenco is an acronym for the Ordnance Engineering Corporation which was founded in 1916 in New York, New York, with a manufacturing plant in Baldwin, Long Island, New York. The company built 16 aircraft before going out of business in 1922. In 1918, they delivered three Model Bs and four Model C1 and C3s, and one Model C2. In 1919, they built four Model Ds and three Model D2 PW-3s, s/n 64142 to 64144.
This aircraft reached McCook Field, Dayton, Ohio, for Air Service testing in 1921 and assigned Project Number P-299. A few flight were made but it was determined that the aircraft was not airworthy. Of the three ordered, this was the only one delivered to the Army."
