Riley Twin Navion
A Riley project was to convert the Navion to a twin. The Twin Navions started with two 140-hp engines and graduated to 150s and finally to 170s. He built 15 of the airplanes at his Fort Lauderdale, Florida facility, and 85 others for a total of 100 were built in Greenville, Texas, by Temco (later the "T" in LTV).
In December 1953, Temco acquired the Riley Twin Navion program
