I somehow cannot believe that you are holding one of Fed's actual frames...
The last info I had regarding his frames was that Wilson send the rackets straight to P1 without a grip pallett whatsoever.
It is only there-at Priority One- that the custom grip mold is applied to all of Fed's rackets and also the balance,weight etc is tweaked there, not at the Wilson Pro Room.
In addition, Roger has P1 leather grips installed,not Wilson.
