Best of British is gun porn - D. Grant has gun photography down to a science while Vic provides the model's stats. There's some trade and gunmaker detail scattered throughout and in the appendix. I have this book on the coffee table next to a big comfy chair, because it's always fun to page through - even for non-gun lovers. Don't get me wrong, I love the book (and it's not so over the top like British Gun Engraving) I just don't keep it in the library as a gun reference.
Gun Craft is the opposite of the above. Good history and lots of technical explanation combined with some fine photos, for reference. You gotta love the science and art of fine shotguns to have this book. I read it twice last week and have dog-eared pages for reference.
I don't have a lot of intrest in the Paradox guns so I can't help much there.
Madness is a sad but very interesting "you can't make this stuff up' kinda book. Poor ol' Gordon was more than a little off center, but the man had a passion for collecting guns - and a lot of other expensive stuff.
I'll still take Vintage Guns for the Modern Shot over all of 'em.
I don't know if you have all noticed but a number of good books have been released recently. I have read the following and can recommend them:
Best of British by Vic Venters & David Grant
Gun Craft by Vic Venters
Paradox by Roger Lake & David Baker
Magnificent Madness by Donald Dallas
We are spoiled these days for quality written work on our favourite subject. So if you have a birthday coming up - tell the kids/wife/dog to get you these. Many hours of interesting and informative reading there.
