Belt seemed like an interesting fellow in a Tom Swift kind of way. The Biographical Record of Jasper County, Missouri describes him as a jeweler and machinist in Fredonia (current pop just over 2,000.) He is listed on the Worldwide Registry of Auto Manufacturers as having made his own car around 1904-1907. Popular Aviation in 1930 covered the “garageman” because he made his own airplane with a recycled Ford Model T engine. His shop, powered by propane for “pennies a day” was considered interesting enough of its own account to earn separate mention at least twice in machinist and blacksmithing journals.
We wouldn’t be surprised if a 1930s dirigible journal also noted Belt with his own zeppelin design that he used to fight off hordes of flying robots backed by foreign parties unknown. Maybe that one just hasn’t been digitized, yet.
