RAF Bomber Command camouflage & Markings book

[oldgit]

Chaps,

I'm looking for a good reference for camouflage & markings for RAF Bomber Command throughout WW2, on a par if possible, with the 'Scale Aircraft Monograph' and 'On Target' series of books already published on the BoB, Pear Harbour, etc.

I remember Bombing Colours by Michael J.F. Bowyer many years ago. Is it still considered a valid & accurate source, or is there something better out there?

Thanks,

Tim
