Hey Bruce, where have you been? Good to see your post.
As to the burl, I used to have some like that from SE Asia or Australia, but I have forgotten the name since I have been back home. Very blondish / light tan. If I remember it, I will repost. However, someone here will beat me to it.
Didn't know we were having a "Guess the Blank" contest for the Summer Extravaganza.
Seriously, good to see you out and about. No clue as to what wood but great pen. Did you do the casting?
