Can anyone help me date this tobacco. I found it (full) at a junktique store. I notice the key difference vs current labeling is that mine says "Blended by Charles Rattray" instead of "Blended for Charles Rattray". It might mean nothing - just thought someone could tell me if I found something good. the Spinnaker is full but the seal is popped. The tobacco is like a brick - still in the foil and untouched.
