On 15 June 1937 the glider was ... flown for the first time ... flown 285 times by the end of the 1937 gliding year ... continued in service until the club disbanded with the outbreak of World War 2 in 1939. Even after the club ended, Art Larson kept the glider flying for many more years." Quotation from the Galt Museum archives; more at https://collections.galtmuseum.com/link/descriptions76210.
