This is called the Unsquashable Jahangir Khan Hero squash racket, part of the Unsquashable range:
Spotted this in October 2016. This is 10 grams heavier than the Unsquashable Tour-Tec Pro, which also has a conventional head shape (they may be identical but I can’t tell for sure from the pictures). Thanks to Alex for the tip.
Frame Weight: 140 grams
Head size: 500 cm sq
String Pattern: 14 x 18
