To all those that are concerned about the legality of my digging I can confirm I have permission of the appropriate people as these come from a search on a former german airbase for historical purposes. The picture also was.taken on the site. By now thay were removed by my collegues.from the bombsquad. They are not near my home, I'm not allowed to take anything I find home. It is a.project about the history of the former german occupation. The question I posted about what they are is purely for administrative purposes in my private notes on my finds. I am very glad to see that people are so concerned about the safety and legality here, as a lot of historical artifacts do disappear into private collections through illegal searching. I hope you will allow me to ask more questions in the future.
