The left half of the same original as photo 348021. This Danziger Luftpost aircraft does not yet carry its Danzig Free State registration Dz-35, but the German registration has been altered with a Z within the D. The coat of arms of Danzig (now Gdansk in Poland) contains two silver crosses above each other on a red shield, so the rudder is red. Photo taken at Königsberg, then in German East Prussia, now in the Russian Kaliningrad exclave. Photo from: ETH-Bibliothek Zürich
