The 1916 Andermat project funding was by Gray Taxicab Co of San Francisco. First flown on 16 April 1916, piloted by Roy Francis, it featured double interplane ailerons, twin tails. One prototype constructed for Army bomber evaluation was shipped to San Diego after this test flight, then reportedly ended up at Kelly Field TX, at which point its track vanished, and the military contract for 21 planes went unfilled.
