Salt,
If you look at one of my posts that I made a while back, I got a type 99 missing the duffel cut. I believe I made the pc out of padauk wood. I also bought some walnut for the task, but settled with wood that was more of a red color. Machining went well with the African wood.

I salute you, since I enjoy fixing up these old rifles. As you note, it isn't everyone's cut of tea... but once in awhile you do find a gem of a rifle that Bubba worked on. I draw the line on restoration if something major was done to the metal.

When at gunshows I actively seek out Arisakaicon's to bring home. If the price is right (sporterized or military) I will take 'em!
