Luftwaffe Paratrooper Badge. Type Friedrich Lindn, Lüdenscheid (FLL)

Zinc based and in a very good, probably unworn condition. The wreath with all of the silver plate still present and dark oxidised. The eagle with practically all of the gilt plate still present and attached to the wreath with two typical rivets.
Not marked but a known variation that has been attributed to the company of Friedrich Linden, Lüdenscheid (FLL).
Difficult to find.
