Information from Johan Visschedijk
Caproni Ca.34 - Like the Ca.33 but in order to gain speed and to protect people from bad weather, the wheels on the front skid had been removed and the fuselage was completely closed so that only the pilots' heads protruded from it. However, this solution was immediately abandoned because the small increase in speed did not compensate for the lost freedom of the crew.
