My friend,, Rusty, who lives in Missouri, sent me these pictures of two Cushman Military Airborne scooters that he recently restored. These are historic vehicles originally built in Lincoln, Nebraska during World War II. They were built to be dropped by parachute. Some of these were sold as war surplus after the war ended and were so popular, the Cushman folks designed and sold a civilian model. The military version is a model 53 and the civilian version is model 53A. Those post war models were built 1946 to 1948.
Rusty says both of his model 53 scooters are for sale.
