Is there a good book available on the Matilda II tank?
Not terribly new ones, I don't think.
There is an old Armour in Profile 15 from the 60s.
There is Bryan Perrett's Armour in Action 2: Matilda (Hardcover, ISBN 9780711004054 Publisher: Ian Allen, 1973).

That's all I could find. They vary in usefulness depending on what you want them for.
