Engines of this type powered the original series 90 Monocoupes designed by Don Luscombe and built by the Mono Aircraft Corp. Monocoupe 90s were manufactured from 1930-40 with various engines, but the Lambert engines were only used on the Monocoupe. When Monocoupe production ceased so did the Lambert engine.
