1940s Marionette Stage or Theater

This item is believed to be a 1940s era marionette stage or theater. The set comes with a stage with four distinct holes for the four yellow poles. It also comes with a top cover that I believe hangs from the four poles(last picture). The set also came with what looks like an animal cage for the marionettes and wheels that look like they are connected to the cage in some way. Lastly there is a board first pictured that came with the set along with a ladder made with rope and blue wooden boards. The final items I am not quite sure how they belong to the set, I've have been doing tons of research trying to locate the answers. Any and all information is greatly appreciated thank you for taking the time to read this.
