I like the reference to Haig, which was probably what Captain America or Peggy Carter would drink - a very popular blend in the 40s and 50s, and the choice of many soldiers at that time. A bottle would probably set you back about $500 bucks or so nowadays.
You can see how old the bottles are here.
The same company make Dimple, which I occasionally drink, but an original Haig is much better because it's non-chill filtered. Dimple is probably the only decent chill-filtered scotch, so I can only imagine how rich it would be without the filtering.
