This is an excellent silver woundbadge maker marked 100 in red case (Verwundetenabzeichen Silber im Etui).
The medal itself has a great remaining silver colour and is in excellent condition. it is on the inside of the base of catch maker marked with “100”, indicating the medal was made by medal maker Rudolf Wächtler & Lange from Mittweida. Maker 100 VWA’s are not easy to find, especially in this good condition.
While the medal itself is in very good condition, the red case is a bit used. Nothing disturbing, but there are some age spots. The most important thing is that the lid is still firmly attached (these are often torn off).
All in all a great set that is getting to find harder these days.
