SM7 Serial numbers

All mine have the same number as well as my AP1’s. I’ve realised it’s actually the order number, which makes sense as they can presumably be traced back to you even if you don’t register them.

Are they custom order? My SM6 custom shaft ordered wedges have the same serial #.

Thanks for the replies.. They were custom order as I had midsize MMC +4 grips added. It makes sense to use the order number for those reasons.

Next question is do all have serial numbers? Or are those without non-custom or tour versions? I noticed on one WITB that there were no lofts or bounce on the pro's SM7's
