Surefit Adapters

I am looking at a shaft with a surefit adapter but there is no serial number on the tip. I was told that adapters off the tour van do not have serial numbers. Is this true? How can you verify it's an original? Aside from putting the club in a clubhead registering machine and reading the head in different settings

Mark,

I personally have had (2) clubs made for me from the Titleist Tour Van and there is no serial number on the tip (adapter).

However, there is a serial number on the clubheads.  I have a 910H and a 910F 3-wood that was made on the Fitting works van. So no serial number's on my tips (adapters).
