Cool! a T205 thread I can contribute to. (I have maybe 20 of them and haven't studied them much. )

My Graham is P25 black sig.

Some color differences can be from the ink mixing, but black was nearly always done with various forms of carbon as the pigment,(For printing inks ca 1911) and it just doesn't fade and didn't need to be mixed.
