The Lawrance Model A-3 aircraft engine was designed by Charles Lawrance, owner of the Lawrance-Aero-Engine- Corp’n, N.Y.- U.S.A, in the mid-1910s. Although designed by Lawrance, manufacturing was turned over to Excelsior Auto Cycle Motor Mfg. & Supply of Chicago, Illinois. The engine produced 28 HP @ 1400 rpm. An interesting feature of this engine was that both pistons worked on the same crankshaft. During World War One, the engine was used on the non-flying Breeze Penquin training airplane. The Penquin was modeled after the French Bleroit X1 trainer, specifically designed to instruct student pilots in the use of aircraft controls while practicing high speed ground taxiing and turns. Beginning in January 1918, 300 Breeze Penguin aircraft and accompanying A-3 engines and Lang propellers were produced. A civilian aircraft, the WACO Cootie, also utilized this engine. The Cootie was a single seat biplane/parasol monoplane; only one was produced.
