So many different variations (including two of my father in 1943!)
SNJ-1 versions of the BC-1 went to the US Navy, while deliveries of the BC-1s to
the RAF started in December 1938, these aircraft being called Harvard 1s by
British Commonwealth air forces. The BC-1A, and subsequent versions, had a
revised rudder shape, blunt wing tips and a metal covered fuselage, with one
exception, which had a wooden fuselage. There was the AT-6B, then came the AT-6C
(SNJ-IV and Harvard 2A) which was redesigned with, among other changes, a wood
rear fuselage in case of strategic material shortages during WW2. But there were
no shortages and the standard structure was reverted to later on. There was also
the AT-6D/SNJ-5/Harvard III, which with AT-6A and C versions and their SNJ and
Harvard equivalents formed the basis of nearly all WW2 contracts.
Talking of stored T-6s. These two photos come courtesy of John Terrell and show
SNJs stored at Glynco in the late 1940s.
