I came across an old packet of free tomato seeds in a 1926 Stark Bro's Seeds catalogue. This variety seemed to be exclusive to Stark Bro's at the time and they named it "Stark's Blight Resister." I am sure seeds for this variety exist somewhere else on this planet, but I could not find any source for it, so I took this experiment fairly seriously, just in case I was the only person in the whole universe with this old seed sample pack.
