A clock made from an original German WW1 period time aircraft propeller. H HEINE WALDMANNSLUST maker marked. Several other aircraft related markings. Original wooden center piece of the propeller. Mounted on four BOSCH marked ignition plugs. The dial does look absolutely period time and matching to us. It is certainly original attached to the propeller. The clockwork however is clearly postwar and must have been replaced later after the orginal clockwork was broken.
