It gives exact location of the leading edge needed for calculation (p.7).

I claimed normal service load:

7.7" at normal service load 1939
7.9" aft limit for DeHavilland without inertia device
7.5" aft limit for Rotol without inertia device

This means that on normal combat load there was only change in the case of the Rotol prop assuming that aircraft was properly loaded.

Besides, the revised limits were originally issued sometime around 41/42.

Otherwise you seem to have chosen same tactics as in the FTH discussion so my part end here now.

Cpt Doggles, you see my point now.
