Mel, my cockpit photo depicts a parasol monoplane, but the following shot is a bi-plane. Your photo depicts a parasol monoplane that matches the wing struts of the cockpit photo.. I think you are correct. It must be the TW-4. Post #7468 is the Fokker S.II side-by-side, unequal span biplane trainer.
