Hi,Just wondering about the position and lack of serial number on the 910h.I very recently bought a 21* 910h with headcover and wrench kit in a lovely titleist pouch from a well known golf retailer in Christchurch NZ.I cannot find a serial number anywhere.I went back to the shop and had a look at other clubs and all of them had a number be it very small or hard to see just behind the hossel on hybrids and fairway wood and drivers. I explained to the shop owner that I could not find one on mine, after seeing the ones in the shop i came home and had another look and with a very good magnifying glass. No number anywhere! none on club head, or hossel or shaft tip nill.I really don't doubt the genuine nature of the club but would rather have one with a number for resale purposes and my own peace of mind. Should I take it back and ask for one with a number? any ideas most welcome.Cheers
