Tim,that may be Manzanita. It is a close relative of briar. During WW2 Grabow made a few pipes that were stamped "West Coast Briar". I have two of them and the wood looks like the Manzanita use by KBB during WW2 in their Monterrey "Mission Briar" pipes.The wood on this one, the guy called West Coast Briar. I can;t find anything on it.
