The AT-12 was designed as a Swedish 2-seat fighter developed from the P-35. 50 were embargoed and taken over by the AAC/AAF as advanced armed trainers with 2-0.50 and 2-0.30's. Another group of Swedish single seat fighters were taken over and shipped to the Philippines as P-35A's.
And KUDOS to you, Stik, for your amazing LIFE-fu skills in finding so many excellent and very interesting reference photos.
