I have found an unopened bottle of Royal Salute 21 blended Scotch Whisky from Chivas Brother, LTD. It is in a greenish bottle(porcelin) with a curved bottom with writing on the bottle that I can not read. The bottom says "Spode England". It is a 750ml (25.4 fl. oz) Bottle with Aberdeen Scotland 80 proof on the bottle. It says "Blended 1801" and the sealed label that is over the top is "S 765410".

Can you give me any information about this bottle, or can you get me to someone that might know something about this vintage?
