Really, you have a 2 part problem here. First, is that the tobacco you've grown to really enjoy is no longer produced. Second, is that the example of it you know and love, was well aged before you ever got your hands on it, and is most likely a completely different animal from the original cut which you can't get anyway.
The girl called back (very nice young woman, and very helpful) and said that the guy she spoke with about it just doesn't know what the English Opulence blend consisted of, and can't make any specific recommendations. There are a few I'd suggest trying, one I mentioned above (Proper English), and another would be the Newminster Ultimate English.
The only other alternative you might have would be to send what you have left to a good blender and see if he can match it for you, but even if he can it won't quite be the same until it has some years on it.
Best I can do for you, buddy, wish it were more. Been right where you are and it's no fun.
