Son took "Ruby The Staggering" for a late afternoon flight. :)
I do believe you are correct. The first 1932 Staggerwings were fixed gear I think in 1934 was the retract and smaller engine model.Jim will correct me if I'm wrong, but I think the Beechcraft 17 was the first with retractable gear. Doing so really cleaned up the aircraft and improved speed and efficiency.
