This trademark has been identified as a House Brand of the Montgomery Wards department store chain. Author/researcher Willie G. Moseley indicates that the unique body design is proprietary to the Airline brand. Models can be found constructed of both Res-O-Glas (a hollow fiberglass body) and wood. Airline also produced acoustic flattop and archtop models. Although several acoustic and acoustic archtop guitars exist, the electric Airline models are significantly more collectible.
