Melt it down? Put it in a museum? Throw it back in the ocean? Is it OK that private individuals own nazi/communist or other evel regime artifacts? I have several WW2 German and Soviet helmets, German gas mask boxes and an iron cross. Nobody ever told me that I should not own it. They are hystoric items , they don’t glorify anything.
There are items with Nazi swastikas in museums all over the world. The uniqueness of this singular item as an artifact of a very particular incident – one in which, it must be remembered, the forces opposing Nazism triumphed – would seem to me to justify its preservation. I don’t think it glorifies anything…but it does have historical relevance.
