Welcome. Lettow!
Discrepancies? More often than you would think, according to the "history" to be found here on our forum.
USFA, after going "all US made," did a marvelous job of producing Colt SAA replicas. One thing that they apparently failed to do was keep accurate production records. A box could leave the factory in two ways; 1) accurately as manufactured or 2) as it was mislabeled. Go figure!
Personally, I would have jumped on any USFA manufactured in June of '08 for $800. Be damned what the box said!!!
