This custom made 1/8 scale Harley-Davidson air cleaner cover was built for Jerry Kieffer’s 1957 Knucklehead model. Mr. Kieffer had asked Mr. Ronnie to make him the air cleaner cover, and this version was built first as a joke, bearing the inscription of “Made in China” instead of “Made in the USA.” Roger also made another air cleaner with the correct inscription that would ultimately go on the scale model Harley. This one was donated to the Miniature Engineering Craftsmanship Museum for display.
