This bowl is like those used in KL Majdanek-Lublin inmates. This has still intact the KL ownership stamping, which is Kgl. Waffen SS Lublin ( this is mean Krieggefangenenlager Waffen SS Lublin for beginning of KL Majdanek camp ) , as these were manufactured in some SS workshops there. Some like this one could be seen in Majdanek memorial museum in Lublin, being exhibited there.
