Need some serious help here! Possible fake Cameron

Wow. I just feel sick to my stomach. In my haste I bought a Scotty Cameron putter from a guy on Criagslist for $200.00 used. It is a Studio Select Newport 2 and is almost flawless...except for this:
I thought I was a pretty good judge of fakes but on the way home I stopped at Golf Galaxy and looked at a few; the serial number on mine looks different. It is directly under the crown on the front, (not the back), and the numbers appear to be bigger than the ones at Golf Galaxy. It is my presumption I just bought a fake.

Any help would be swell, I just feel ill right now. Does the magnet test work or is there anything else I should be doing to authenticate it? That is other than paying $60.00 to Scotty Cameron to tell me it is probably not real.

Thanks!

I will try to upload some pictures....first time so it might not work.
My main concern is the position of the serial number; it is on the front of the putter, not the reverse and the numbering appears bigger than the ones I viewed at the store.
Thanks again for the input.
