hi just looking to get an opinion on the authenticity of my titleist 710 mb irons. i can not fault any detail from the writing and stamps to the wear and bag chatter everyone who has viewed them is of the same opinion. they have the factory fitted S300 shafts and have been re-griped before. I purchased them from a local pro shop worker who is a trainee pro for a titleist authorized dealer. they where supposedly the head pro's clubs when he upgraded to 712's ? now here is the catch there is no serial number on any of the irons what so ever??? both my vockey wedges have serial numbers and the titleist writing matches perfectly. the clubs feel great and play well. I guess i would be a little bumed out if i knew they were fakes and would want to get the real deal. are staff/ tour issue irons issued without serial numbers and if yes what is the reason behind it. I know i should buy new from the authorised rep but they guy talked me into saving alot of money and buying the 710's. if they are fake i would say its pretty un-ethical of someone who works for a titleist authorized dealer. i can send images if required to help verify and if they are fake i would be very concerned as they have fooled everyone who has looked at them. 

thanks in advance Luke
