This is a Verwundetenabzeichen im Schwarz (VWA) / Black woundbadge + LDO case.
The badge is on the backside maker marked with L/11, which stands for maker Wilhelm Deumer from Ludenscheid. The badge is stonemint and can not be upgraded.
The case is very hard to find and in light used condition. It is on the back also maker marked with L/11.
Simply a superset!
