XP-51F/G, P-51H and XP-82/P-82B known technical and testing documents floating around?

[BarnOwlLover]

I've seen the P-51H testing and SAC documents at World War II Aircraft Performance, and some XP-51F/G documents there, but is there anything additional floating around, as well as for the Merlin F-82s? This includes any documents pertaining to the XP-51F/G evaluated at Boscombe Down, XP-82/P-82B testing/eval documents, and technical illustrations and such.

I've been looking but I haven't found very much beyond what's out there at World War II Aircraft Performance and what's shown up here on the forum already.
