Stewart Stunell has recently e-mailed me some information about the 10.10, Besson International, Besson Stratford, Besson New Standard, Besson Academy and Sessionaire ranges. Optional bell entirely of gold brass. All rights reserved. This company was formed from the merger of Boosey & Co. with Hawkes & Son in the 1930s. Established circa 1915 in Los Angeles 1915, initial Olds trombone models all had in-slide tuning. He became friends with Thomas King, a leading trombonist, and the two men collaborated to produce a trombone with superior slide action and tone quality.
