I am not a fan of numericals, despite being a mathematician, but this one does not look quite as tiresome as most do. Having just started, I have F and two alternatives for T. In clue B, one of the Ts makes T - 3F zero. That means that B could be any two digit number (subject to the parity constraint), since they are all factors of zero.
I have the feeling that we ought to be using B to decide that this does not happen and so eliminate that value for T. Has anyone else thought about this?
