Presbyterian Mixture, for example, claims to be from before WWI. What other blends make similar claims? I know I've seen a few.

Walnut and most OTC ,Most of the GH&Co, uhles, Peretti,
Theres actually a bunch that claim to be the same blends from yester year.. I imagine most are dubious claims at best.
