My guess is that the egg itself is made in the Czech Republic while the other pieces are Maltese and shipped to the Czech Republic where the set is assembled.
Having run into the mongol-guys in the boot-sales here, that would be my guess too
Your guy having regular eyes, but with the angry eye-brows and typical beard/mustache of the mongols, makes it quite a unique one! I would think it's a production mistake, which don't slip into the market that often!! Enjoy it, he's really an egg-special!
