This round badge was recovered from the former Luftwaffe Fliegerhorst Kommandantur (aerial military base command headquarters) located in West Poland, called Oels by Germans, but nowadays called Olesnica. This badge is in really good condition, apart from the partial lack of the needle on the reverse. Perfect for display though. Badges like this one were used to identify the military personnel from Luftwaffe who worked into the base. In this case, the bearer of this one was the number 501.
