http://greek-war-equipment.blogspot.com The Do.22 was a German seaplane torpedo bomber that was not used by the Germans and never operated as a torpedo bomber; in fact it was not always as seaplane either.
This is odd, as all information I can find says that there was only one prototype (the version Do 22L) which had a conventional landing gear. Was this prototype exported to Greece as well, or do we see a (perhaps local) conversion?
Best regards!
I found this
In Greek service, they were first used in naval convoy escort, anti-submarine patrol, and naval reconnaissance missions, including searching for enemy minefields. Later, nine were fitted with conventional landing gear instead of sea-landing floating system, because the Greeks were desperately short of army cooperation aircraft. They were also expected to be used for night bombing missions against the Italian forces at Tepeleni, but only one such mission was carried out.
Operational History
1938 - 1939 - Greece receives her 12 Do.22.
December 1940 - January 1941 - 9 of the 12 aircraft are fitted with landing gear in Elefsis (KEA) and are assigned to the reconstituted 2nd Observation Squadron to be used in reconnaissance and night bombing missions

This site also has an un-colourised version in the aircraft with wheel fairings
