One photograph of a trumpet making workshop titled 'Back street musical instrument makers'. The focal point is a single worker polishing a valveless silver trumpet. Other workers are clustered around the workbench, working on their own instruments in the background. Caption on back reads: 'The back street workshop of Mayers and Harrison Ltd., who have the important task of making for Her Majesty's Government silver State Trumpets to be used by the Household Cavalry. Story A. Palmer'.
