Michael Shackleton at Trackpad Publishing, in conjunction with Mike Starmer, has recently released a book on colour schemes of the wartime Tilly. As the 'blurb' says, the information is applicable to many British Army vehicles of the period, not just the Tilly.
Details about the book can be seen here:

I have many of Michael's publications, and he did an outstanding job publishing my Leopard AS1 book a few years ago. Although I am yet to see a copy of the Tilly booklet, knowing Michael, I'm sure it will be up to his usual high production standard.

(yes, I know the seller! Yes, he's a mate of mine! No, I am not getting any form of reward for bringing the book to the attention of MLU-ers)
