Recently found on eBay. An original set of WWII Semaphore flags and an information booklet.
The "Aide" has a slider paper, between the two sides, with two small tabs on either side. It pulls down almost the length of the"Aide".
In doing so, the tabs line up with various pieces of information. All Navy stuff.
The slider is slightly open to show some information--both sides. Larger and it would not fit my scan bed.
