Luftwaffe Pilot Badge in Envelope. Maker BSW.

Zinc based and in an excellent, unworn condition. The wreath with all of the matt silver plate still present and some patina. The eagle with most of the dark oxidised finish and attached to the wreath with two typical rivets.
Marked on the reverse with „BSW“ in a cloverleaf for the company of Brüder Schneider from Vienna.
The fitting light brown envelope in a good, somewhat used condition. Printed on the obverse with the designation „Flugzeugführer-Abzeichen“, and on the reverse with the fitting maker „Brüder Schneider A.G. Wien VI“.
Very difficult to find set with only few known in collections world wide.
