N80013 (cn 04297) A converted DH-104 Dove, this turboprop aircraft carried the designation of Riley Turbo Exec 400. Operated by Fischer Brothers Aviation, operating as Allegheny Commuter, it is seen on the ramp at Galion Municipal Airport, west of Mansfield, OH. Guessing the time frame to be around 1970. A newly acquired postcard from my collection.
