Bought this thinking it was a Holmegaard Kluk, it's water stained so at the moment am trying the old Steredent trick hence the cloudiness. The pontil is ground out and polished, the odd thing is the stopper is not totally cloudy from being ground against the decanter and neither is the decanter, they both have clear bits which might seem as if it is new but there is wear to the base. Help please.
