Ken, Viggo has been making wood bottoms the last year or so, and they are first rate, another member GT made them also, but has suspended making them for a while.
The books by Jan Still are some of the best for overall information, there are four of them, covering each "era". I personally have many other Luger books besides Jan's, each is good in their own right, Kenyonâ??s has good pictures, Datig's has good stories and information, Jones has good information. The last two are much older, so there is some inaccurate info in them, but still worthwhile.
BTW, Jan's books are around $70 (including shipping), so they are a bit cheaper than the $600+ for Clawson's books,
