The production of Wurlitzer organs ceased in 1939, the last organ to leave the factory being a style 165 organ in a 157 case (done because Wurlitzer had an extra 157 case remaining in the factory and the owner didn't mind the change). During the Great Depression leading up to the end of production, various cost-cutting measures were made, such as the substitution of brass horn and trumpet pipes for ones made of wood (though arguably the change from brass to wood may have been due to the shrill sound produced by the brass pipes which some people may have found unpleasant; wood pipes produced a mellower sound).
