Years ago at Camp Perry, I met quite a few people that lived in Hawaii. They introduced me to Koa Wood. I made a full Koa stock for one of them. You can not cut a Koa tree down for wood, but you can forage for downed trees. One of theses guys set me up with a place I could get Koa at a reasonable price. This is the last full piece I had. I have pieces left to make a couple laminate stocks mixed with other woods. Thumbhole stocks are a bit more difficult on the body to make. I complete understand why Anschutz no longer makes them. The pistil cap is Thuya wood (someone took an out of focus picture, good thing his woodworking skills are better).
