Despite the fact that the original materials were not duplicated and the Carlson model is built with a fiberglass fuselage over a welded steel frame, with a tailcone made of 2024-T3 aluminium (an aluminium alloy used in applications requiring high strength to weight ratio), supported by internal bulkheads, Carlson set out to build his replica as closely as possible to the original, working from the only surviving documents, some sketches, a few photographs and one three-view drawing.
