My experience with CZ wood stocks is that CZ uses mud to finish their wood. Whatever material they use covers up any character the wood may have.
Strip the stock of its original finish with paint remover, sand and whisker the wood. Use Minwax natural stain to bring out whatever character the wood may have. Go here: http://www.thehighroad.org/showthread.php?t=240961
for instructions on how to apply a great finish. (not easy, but well worth the effort)
The photos are of my CZ 452 FS refinished in a similar manner to what I suggest.
