Breguet 14, CZL Propeller

Nice group picture with Breguet 14 aircraft fitted with CZL propeller. It looks like one of the early ones as except typically used ash also some darker wood was selected. Picture taken in Bydgoszcz or in Dęblin (in this case it  would be 1928 or after). Picture presented thanks to Robert Gretzyngier

Period Advert. Renault Engine. Inter-War Period.
