What other breed & gender is this Exchequer Leghorn Cross?

[Cerci]

Pullet or Cockerel? 13 weeks old Leghorn Exchequer Cross(?) Any one prepared to guess the cross (if any?) Never seen a grey & white exchequer before, nor have I been able to find a picture of one on the internet.. any heads up would be appreciated!
