I know these items are real as my Grandfather was the vet who brought them home. He passed away a couple years ago or I could find out more about them.. The belt and buckle are intact and in very good condition. It’s a sawastica inside a shovel head surrounded by 5 grains. The helmet looks painted black, a bit rough, with a scattered whole in one side probably from a shot..I’m trying to figure out their approximate value. Can someone help me please?
