Tigerwood and Zebrawood are two differnt woods, generally zebrawood is alot blonder whereas tiger is darker. x2 on the look up of the 1969 Bear K Mags and Hunters for some stunning examples of tigerwood bows. A hand full of 68' k hunters can be had in tigerwood as well. In general tigerwood is harder to come by in the old bears than zebrawood. I personally think that the 1969 K Mag in tigerwood with the black glass inlays and tips is the best looking of the k mags.
Wish I had some pics for you but I don't. Example of both can usually be found on the big auction site. Zebrawood can be found in old grizzlys, polars, alaskans, tigercats, k specials, little bears and others. As far as I know the tigerwood is only found in the 68 and 69 k hunters and the 69 k mag.
