ok so reading this I did not see where the letter was on top on W.T & Co? did I miss it?

Look at page 5 bottom of middle column seems to describe your mark with the A / W T CO/ etc. including the less common CO capital O. If so, makes yours around 1888, but who knows. Safe to assume late 1800s through 1901 or so.
