I'd like to buy my friend's N90 Gen 1 racket, but he don't have Head Cover (lining 16 digit code) anymore. So, can you guys help me to verify the racket real or fake with these criteria : - at the butt cap there is Lining logo with Silver color (no S2 sticker). - Shaft Code (near Control Support Cap) is KTT S2 - Yellow Green Hologram sticker with Lining logo and stars inside and also has a code : M044643. - overall the finishing qualtiy is good (very smooth).
