I purchased a new 8.5 driver and three wood from my pro shop here in Germany on Ramstien air base recently, and noticed that the serial numbers were not there. My question is should there be one? I know almost all if not all Titleist clubs have one. Also they were ordered directly from Acushnet Europe ltd. which I see is listed in the company contact list. I even went back to check the other drivers and woods that they had in stock, and none had a number. Is there something fishy here or is this normal?
