Buckers had strange landing gear geometry in which the struts jutted forward, and to my knowledge no Bucker product ever had outrigger style gear - that is a late 20's/early 30's design fad - early Waco's, Stinson's, Great Lakes, Stearmans, and Travel Air's had them among other makes. Another give away is the tail. I think you were fooled by the wing sweep and the inline engine. The early Great Lakes airplanes had Menasco Pirate's. I believe this example pictured has a 200hp Ranger. In my mind, the old inline GL's look the best, followed by the ships powered with 185 Warners (ala Harold Krier), and some I have seen with 220 Continentals (although that engine and prop set look "too big" for the airplane).
