Well, I am now in receipt of a pair of Wimbledon Graphites. Indeed, it's the same model as used by Joakim Nystrom and Mikael Pernfors, but the pair I purchased (one that has been modified with ample lead at the sides of the head, strung with natural gut; and one seemingly unmodified one that had never been strung, but now is) appear to have been earmarked for Rodney Harmon? (There's a sticker on the unmodified, NOS one that simply is marked, "Rodney.")
Lovely frames, perfect head size (88 square inches; looks larger as it is wider - closer to round - than most elliptical 90's), great quality. The original Wimbledon calfskin grips (in massive size 5) are Wimbledon-branded, but appear to be the same as the best Pro Kennex grips used concurrently - no surprise there since these Wimbledon frames were openly made by Kunnan, and marked as such.
I'm taking them for a hit tonight; can file a report if there is any interest.
