Cool...great geeky info for us bourbon nerds. They've always tasted very similar except for age (the Seagrams and early Sazerac stuff that is) and I sure wish the dusty Benchmark in the bunker was more than 80 proof too.
If it's the old round bottle instead of the Benchmark Single Barrel (never mind McAfee's) then it will still be tasty. Not sure that even the Seagram's-labeled version was ever produced at higher than 86 proof.
Time to renew my quest for a L'ville ER 10/101!
