I have the physical flight manual for the Lanc from 1944, if that would help with development. It's got all the details of flight capability and the changes made later to the manual, the quirks and the dos and don'ts.
I also have the general flight manual for RAF WW2 trainees but it doesn't have many pages... funnily enough.
Let me know if you'd like me to send all the pages of the Lanc manual, it's got photos of the cockpit and labels for the controls, with glued on cutout corrections that were later added. I can only send it around May 16-17 as I'm rather busy 'till then.
