Just spotted the Unsquashable James Willstrop Autograph on the Unsquashable Website. Thanks to Alex for the tip!
This is a rather light 125-gram racket in a teardrop head shape. Even though this is called the James Willstrop Autograph, James plays with the Unsquashable Y-Tec Pro currently.
Head Size: 500 sq cm
Frame Weight: 125 grams
String Pattern: 14 x 18
