Luftwaffe combined pilot observer badge by Friedrich Linden, Lüdenscheid. Tombac wreath with riveted tombac eagle. Unmarked typical early to mid war production by FLL. Outstanding condition with polished sparkling highlights on the wreath and white-silvered eagle. Badge shows very small signs of age. No repairs, no damage. 

(scans show that the finish looks different on both sides of the wreath but in hand that's not a fact)

One of the best FLL PO's I have had, a true jewel!
