The all-wood SIPA S20 was what a retractable Messenger might have looked like if it had been designed by a Frenchman! The upwards-opening cockpit cover with spinal hinges and the over-the-shoulder side windows and the projecting flaps and twin-fin tail unit also had similarities. The display board gave the engine as a Mathis G8R, a 200 hp 8-cyl inverted vee in-line air-cooled engine for which the upwards curved cowling with intake under the spinner is appropriate. The propeller was a 2-blade wooden fixed pitch right hand tractor. Nothing more was heard of the S20.
