Olds (famous for its brass instruments) was awarded a government contract to supply instruments, including saxophones, to the military during the 2nd World War. A large number went down with a supply ship in the Mediterranean, and very few of the saxes survive today. There is some speculation that the instrument pictured here, with it's low serial number, may have been a pre-production model - either made to demonstrate the factory's capabilities to the government, or because Olds was trying to break into the professional sax market. Several unusual features can be seen in the photos.
The silver tone ring (like those on brass instruments) reads:
"Super Olds made by F. E.Olds and Son, Los Angeles, California U. S. A."

The B and Bb keys are on the left side of the bell. The keys resemble flute keys, with their dimpled centers. The resonators are "rivet" style.

Some of the features resemble pre-war Martin Saxophones:
beveled tops of tone holes; all keywork, tone-holes and body joints silver-soldered.
