Hi Gaspare, I have one piece in my own collection. But sadly it is a ground find so the quality of details is not so good. It was hardly crushed and had to be heated and straighten. It was found in the surrendering area where German soldiers were throwing away their equipement including badges, buckles and also rings, etc.
