OK, Lets make it more complicated - though maybe Leon can sort this out when he gets out of hiding.
Leon sent me Sal's cuttings in 2004. After moving, Leon wanted to re-establish a Sal's tree, and had gotten cuttings from someone else. But he did some research, and concluded that the tree I have was the only verified tree which had been a progeny of his original tree, and so I sent him cuttings of my tree, so that he could once again have "his" original tree. So, his original tree, and thus mine, are the same. If mine is EL, then so was his original tree, but he claims (acc. to the GW post) that his was from a different source (not EL). That would also make his original source, and the EL source the same.
Preliminary DNA testing at USDA / UC Davis indicates that it is the same tree as my Dark Portuguese. They are similar, but I am not ready to say that they are identical. They are both similar to my HC.
