You could try The Mosquito Page at:
The de Havilland Mosquito Page
The Forum users (which includes some Mosquito aircrew and some absolute experts on the aircraft) either know or can find out most things about the Mosquito. They are also a cracking source of stories and a search on the site, or a query, might throw up all sorts of interesting tales about Mosquito assymetry.
Alternatively, in the 70s and 80s, Crecy published copies of the Pilot's Notes for several variants of the Mosquito and you might be able to find a copy somewhere.
