Those tools could go back to the 541 of the early 1920's. The two wands and brush go together. I am not sure of the crevice tool. Hoover used these tools until 1935 with the last of the 825's. In 1936, they started using lighter weight materials for their cleaning tools. There would have been some sort of converter depending on the model, a crevice tool that was shorter, and a cloth covered hose. All of this would have been served up in a brief case type carrier with a metal latch.
I would hold onto them as they are getting more difficult to find. Thanks for the photo.
