The Camair Twin Navion was not a particularly successfull attempt to improve upon the well-liked, but slightly under-powered, Ryan navion. In the end only 33 examples were produced with this one on display at the super mid-Atlantic Air Museum.

This is a rare aircraft type. The Camair 480 was a twin-engined conversion by Cameron Iron Works Inc of the North American Navion, which was built later by Ryan. This example was built in 1946 as a North American Navion, then converted to a Camair 480 in 1956.
