I posted a picture of this racquet in the Goodwill thread, and some of the more knowledgeable board members have seen it, but there is still some mystery as to what it is and when and why it was made: Item: Wilson Chris Evert Graphite with an Isometric head. I picked this out of the bin at a Salvation Army Store in northern Vermont. Weight: 11.25 oz or 318g Material: Graphite Composite Head: Labeled "midsize" Bumperless Buttcap Code: SKZ Beam: 17mm, constant Pattern: 16/18 Grip: 4 3/8 (SL3) Balance: About 4 pts head heavy See pics below. Any ideas? Did Wilson make a quick little trip down the isometric design path when Chris was being dominated by Martina in the early/ mid 80s? Is it possible the this is a repainted Yonex? I am assuming at the very least that the detail and graphics should narrow the manufacturing date possibilities down to a small range, right?
