or domestic chicken leg tag. depending on size.Please supply size info.
Looks like a leg band for a carrier pigeon, but not sure how big it is.
I will try this way, thank you!Two long shots are:
1) Contact Athinaios Historikos who posted the photo here
The caption is "Athens in WWII | Two contrasting photos from the beach by Cape Sounion, the first from the German occupation (German soldiers washing military vehicles) and the second from the present." They may know the history or know someone who does.
2) Ask some older residents in the area if they have heard of "Quetta" .
Good luck!
