Well i officially stumped the German collector for the first time ever. No one knows

Doubt its a war item.

It was made in Germany, so that limits the years of manufucture.
Door 1.Philadelphia and the number has to do with what it was used for and by whom.
Door 2. The container contained a product made in Germany and shipped to Phialdelphia.
