Tom,
I took many pics at Cosford of the Hampden project( see the walkaround on LSM). And have a lot of books but
Still you have to make conpromises.
A Sunderland eh, that would be great. But that Stirling, I have a fully illustrated manual. If you take on the
Stirling, I mail you scans with everything you want to know.
After you finish the Hally first of course.
Cees
