I wonder if the "Missing" 5 January AT-7 was actually a confused story that was generated by the recovery of the crew of the Barkley-Grow T8P-1. They turned up on 2 January 1943 after they went missing on 22 December 1942. (Their plane actually looks like a Beechcraft AT-7. )
Here is a little on the Barkley-Grow.
