Need some help, I can't find out nothing about these, This is some kind of enemy plane gunnery globe, i have six of these, the planes are mounted on a rod and go inside of the globe, there are colors on the globe that coincide with the guns on the plane. The planes are lead on steel rods and have the type and date under the wings, they are dated 1/43. The Globes are plastic and not marked. They also have a info disc that goes on them
I have no idea what these are called or what there used for. Google turned up nothing. Could use some help.
