By 1941 Olds held al least six patents for trumpet and trombone design.Since 1908, F.E. Today these are very rare as they were not generally available to the public and a large number of them went down with a supply ship in the Mediterranean. During World War II, the government had Olds produce saxophones along with the more standard strategic production. The Recording model trumpet and cornet were probably designed shortly before the war halted production. There were also some french horns made in the late 1930s, although they didn't appear in the catalogues at that time. This is likely the first production bass trombone with two valve levers. The Super bass trombone could be had with two valves, both actuated by levers. This was the standard finish for the Military line. All but the Super models could be ordered with a distinctive hammered finish on the bell. Other models introduced in the 1930s include the Special, Military, Symphony and French models. The Super Olds line of trombones, trumpets and cornets was introduced in about 1932 and soon became legendary. These new trombones apparently met with success quickly, and with the help of Earl Strickler and Earl Williams, Olds expanded production to about 200 a year and moved into a large facility by the early 1920s. Most Olds trombones were made to order at this time. Model designations were Solo, Small Medium, Medium, Large Medium, Large and Symphony, which did not indicate a particular bore and bell combination, but a relative size. From the earliest years, he was offering a variety of bore sizes (.485' and dual bores from. Implementing new ideas patented in 1912 (some of these are incorporated in trombones today), Olds started producing quality trombones on a small scale. It was probably about this time that he first offered his new trombones for sale. This early work was done in a small workshop behind his house, which was just south of downtown Los Angeles. All along experimenting with trombone design, he was repairing band instruments full-time by 1910.
