Strange Leitz box.

[Erik van Straten]

A friend of me showed me this box. He posesses it for many years. However, he does not know what the use of this thing is.

Please, help us!

It is a round piece of glass, beautifully polished, in a small wooden box, about 5 x 5 cm.

Thank you, Pan, that must be it! Great!
