Difficult to tell via a few pictures. I have sent the images to a colleague in the US, but the best thing to do is to speak to your pro, ask them to contact our returns department and request a collection of the putter to be authenticated here in St Ives.
It looks like a retail Oil Can with yellow dots added to look like the Tour dots sometimes seen on Tour Camerons, such as this one: http://www.scottycameron.co.uk/authentication/registrysearch.asp?registry=A016270
Putter looks genuine enough, but the dot is rather questionable.
Surely there will be a serial number on the shaft or hosal that can be checked on a production data base? i know all my Titleist clubs have serial numbers on?.
I believed that older style camerons didn't have any serial numbers, only recent putters such as the 2013 select line?
it looks real
