Webley MkIV - VI need reference material

[RogueSniper]

Lately I've been considering getting a Webley revolver but I need to do more research. I prefer textbooks to the internet. Can anyone make some recommendations?

I'm considering the MkIV, MkV, and MkVI. I've seen some great looking examples at Shows and some LGS.
