Marks 21 point was that the two are not related. They are not. I know nothing of the current seller. The Las Vegas event involved a legitimate gun which was sold via an internet transaction, but not delivered and was being shopped around for sale after the original payment had be accepted.
My point is that the barrels are either replacements or part of a factory issue 2 barrel set and the second serial number, being earlier than the original, is unlikely to be the result of a return for repair or alteration.
