This is an excellent silver woundbadge maker marked L/21 in red case (Verwundetenabzeichen Silber im Etui).
The medal itself is in very good condition for this maker. it is on the underside maker marked with “L/21”, indicating the medal was made by medal maker Forster & Barth. Maker makerd L/21 VWA’s in this setup are quite rare to find, especially in this good condition.
The case is in good condition too, with on the underside the typical salt and pepper color stripe pattern.
All in all a great set that is getting to find harder these days.
