I was at the Palm Beach, BJ auction a few weeks ago and looked this car over. If I remember correctly the seller had a notebook full of pictures and ALL of the MacNeish report there to look through. Page two clearly stated that the engine was not the original. It also clearly stated it on the windshield description. So the seller at the auction was honest about the restamp.
Obviously the new owner is just another typical crooked scammer that conveniently only shows the "Certificate of Authenticity" page of JM's report and not the full report in there ad to deceive and try to make some quick money.
Like we always say, "I sure hope people are searching these VIN's before they buy"
