1914-1918 Pilot badge by unknown maker, "Prinzengrösse". 46,5mm tall. Massive silver construction with soldered on set up. Apart from the "800" silver content, unmarked. Very nice detailed obverse. Very good condition with only very light traces of age. No damage, no repairs.

Prinzengrösse refers to badges that are 2/3 of the normal badge size. Prinzengrösse pilot badges are extremely rare!
