I've got the Knuckleduster firearms book you're talking about -- just got
it today, in fact. It does have guns I didn't cover in LAW DOGS, and more
importantly it has pictures of the guns it describes. I'd say it's probably a
worthwhile buy for dedicated DL players. :)
I'm not so sure how good the DL conversion notes are, but then I've
really only just glanced at them.
