maybe I’m getting the wrong end of the stick, but I’m sure people many times more knowledgeable than me will correct me, but I was under the impression that WK163 was a B.(I)6. Possibly a converted B.2 to B.(I)6 configuration? Having read your recommended site bex it looks like she is probably closer to being a B.(I)6 than a standard B.2, what with B.6 wings, engines and nose.
