From what I could see, this one didn't appear to be marked at all, and if it weren't "brazilian green" (green and bronze), I've got to admit I might not have considered that it could be an Eversharp. But according to Cliff it is, and I certainly believe him, because he had the whole set:
That pen converts into a matching desk pen, too. According to Cliff, the only thing missing from this ensemble is a short finial that you could use in place of the taper on the pencil, so that you could use it either as a desk pencil or as a golf pencil. Talk about going from one extreme to the other!
