I would go to the source. On the bottom right of this page, click on the Scotty Cameron logo. It will take you to his site. Once you are there, click on his customer service page at the bottom of that page, believe it is on the bottom left. They should be able to help you, they are the source and the experts. We are Titleist loyalists like yourself on this site. With respect. Hoping it is real.

@CNicolas I had this same model putter for a short time when I was experimenting with putters and everything on yours looks legit to me. No worries on whether it is authentic. It’s a great putter, hopefully becomes a gamer for you.
