The photos show a cardboard box, manufactured by Rittman, Ohio. Possibly in 1944.
Apparently this box used to hold 3 types of Tellermines.
These mines might have been US made for instructional purpose.
What do the red triangles mean, and what is that red "E" on its side?
If anyone know more about this, please send an e-mail with info.
