Nice! I like your Weir evolution concept Jon.
Maybe a first stab at the Weir W.6 design is single-rotored. Then, James Weir decides instead to refine his twin-rotored W.5 of 1938. This enlarged W.6 (II) design was more in line with Heinrich Focke's 1936 Fw 61 (later Focke-Achgelis Fa 61). When George Miles of Miles Aircraft made inquiries at Cathcart about the Autodynamic Rotor Head, James Weir was happy to sell Miles the rights.
Once FG Miles approved the sale, Maxine 'Blossom' Miles undertook the redesign of an M.14 Hawk Trainer III airframe to accept the ARH. Initially, known as the M.14G, the autogyro was later redesigned G.1 (in Miles Aircraft's new 'G for Gyro' category) and renamed Gyromagister (to be in line with the rebranding of the fixed-wing M.14 trainer).
As for the second incarnation of the W.6, the outbreak of WW2 ended its development. Plans for producing W.6s at Abbotsinch were finally abandoned for good in 1940.
