Not to be a butt head but its not TH73 it's TG73 (After Tony Gaziano). DG20 is after Dean Girling. And I forget what the others stand for......because I'm old and I'm usually having a martini while I'm on here at night.
And, for you last minute Christmas shoppers out there, I do just fine in all G&G lasts in a UK7.
Isn't it DG70?
