This is a vacuum dusting tools accessory kit that came with a HOOVER Model 475 vacuum cleaner from 1935-1936. I don't know if it is original to the vacuum cleaner, but the attachments work just fine and the instruction sheet has the NRA (National Recovery Act) CODE seal of approval on it. The NRA was in existance from 1933 thru 1935, so this accessory kit is most likely from the same period as the vacuum.

These are the instructions that were in the accessory box. It is a single 3 page foldout sheet.
