1900s old serif

Which early 1900s »old style« Caslon revival is this?

This is from a 2008 political science book published in Germany. It is pretty decently designed, compared to most other publications in its academic field, the typographic standard of which is pretty low these days IMHO (in Germany, that is).

(sorry, no better qualitiy available)

The typeface used looks one of those Caslon revivals, c. 1900; Binny/Bruce/Monotype »Old Style«, etc.: the T, E, the g, the Q, the numerals... but which one is it? Monotype Old Style is close, but it's not quite it. I've had a look at several »proper« Caslons, but none of them had that Q. What's weird about this book, by the way, is that there's no italics it.

Can walbaum be used successfully as body text?

I've been looking to try out walbaum in an editorial project for some time but still am unsure of its suitability as body copy? I usually go for the safer options of minion pro, sabon or caslon but have been meaning to try out this beautiful typeface. For arguments sake the type size would range from 8pt to 12pt. I hope someone can give me good advice, thanks.
