When I got my clubs, I’m sure I fully recorded their details including registration numbers. Now I can find my clubs but no details of the registration numbers. I need to find the number of my putter, as it has “gone missing”. In a custom headcover too! I have correspondence with Titleist from the purchase in 2013, but again no number. It’s a 2012 Notchback built with heavier weights and is irreplaceable…
