Brett bats come up all the time on this forum. I bought one from Andy Benish at vintagebats.com. He has a section on Brett bats that is a must for anyone looking to purchase one. Brett characteristics are just as important as matching factory records. I think a HUGE telltale about this bat is that it has no ball marks. George Brett could hit! I would email Andy and see what he has to say. I would personally be leary about this particular bat as being game used. As well as the others have mentioned, the weight is a very important aspect to check out. The pine tar amount should also match with the amount of ball marks. The more the tar the more ball marks should be present. Good luck.
