This listing features a vintage 1958 Wen-Mac Challenger / Turbojet Model 106 engine-powered airplane. As found. Sold as is. Not tested. Dimensions are 14 x 18 x 5 inches. The airplane appears structurally intact but is dirty with grime and discoloration on the off-white fuselage. The .049 engine shows some oxidation/grime, and one wheel is detached and loose in the box. Control lines are tangled, while the plastic canopy is intact but may be yellowed. The original box is in poor condition, with torn and creased edges, warped corners, and significant wear. Inside, the cardboard insert is heavily torn. The included 'Owner's Manual' and instruction sheet are yellowed, creased, and stained from age. Collectors will appreciate the original box and paperwork despite their poor condition. Please note that the functionality of the engine is untested. This is a unique piece of memorabilia from the Wen-Mac Corporation, a well-known manufacturer of model toys in the 1950s and 1960s.
