Vessel Hull Number-Did I get scammed?

[JBASS02]

I bought my first Seacraft('72 20') yesterday. Needless to say I'm super excited. Transom and stringers seem good, however there are lots of cosmetic fixes to be made.
So here is the problem... I was trying to look up more information about this particular hull/model and looked to the title for the Vessel Hull Number...BNV386KE... from what I've see this isn't a Seacraft Hull Number??? Did I get scammed??? The title states the builder as Seacraft. I've looked through photos of other '72 Seacraft and everything looks the exact same. The thru-hulls, compartment layouts, openings in gunnels all match other 72 Seacraft. Could the hull number have changed? Any advise would be greatly appreciated. I'd like to be certain before I call the seller.
