I recently purchased a set of SM7s all new a sealed but from a less than credible source, they have S300 shafts instead of the stock S200 and also an older style BV grip rather than the stock Golf pride cord. Both of which can be explained due to a "custom order"
My biggest worry is the style of serial number used, it appears to be pinned in like older Vokeys and similar to others I have seen on irons and drivers. All the SM7s I have seen have a smaller font with almost a black paint fill for the serial. As per photos.
Any help much appreciated.
