Salsbury scooters date from 1935 and one of their early innovations was the Continuously Variable Ratio Transmission. In December 1945 Salsbury became a subsidiary of Northrop Aircraft and the Model 85 scooter (as seen here) was introduced in May 1946. Northrop sold Salsbury in 1948, to the Wayne Street Sweeper Company(!), which continued to sell scooters assembled from spare parts. In 1954 the company was again sold, to Emery Engineering, who continued to assemble scooters from parts. About 700-900 were produced in total.
