Hi.

I have had this for almost 20 years now, but I forgot that I had it untill a coupple of days ago when I found it again in my basement.

I really have now idea what this is since I mostly collect medals.

Can anyone please tell me what this is, what is was used for?
What does the stamp mean?


Best regards,
André
