I have a question. You are saying that the Parachutist badge was made only by Junker. But I found another manufacturer, Friedrich Linden. What is known about him? Next, see the photo. The wreath fastening tape has 4 rings. I think the badge review is not complete. What can you say ?
The first photo 4 rings
The second photo - this is Silver badge
The third photo - this is Friedrich Linden
