Taking out old lower cabs, I found a nearly new wooden pencil. Underneath everything so its got to be at least 40 years old knowing what I know about the house history. Didn't think anything about it until I started to use it. The lead is so strong i can press hard enough to indent hard maple. New yellow ones just snap trying that. No identification, it was evidently a give away. Round, off white with a kind of paisley pattern printed on it. Wish I had a carton of them.
