From the item description:
ORIGINAL 1984 WHEELJACK MINT SEALED BOX, NOT A CHEAP KNOCK OFF, METAL COMPONENT'S STAMPED 80-82 JAPAN
If the item is MISB, how does he know what date is on the metal parts?
Oh dear. While the bootlegs are becoming sharper, the scammers are getting even dumber. Maybe when he says 'NOT A CHEAP KNOCK OFF' he means it's an EXPENSIVE knock off.
