On site are most of them with "T" + number. But according to most of czech Tatra enthusiasts, it should be just number, without T. May I delete the T's?
Yes, that is the point of misunderstanding - there are two variants of signs - with brand name and without it. So for example the same car is Tatra 603 and T603

Like "Alfa Romeo 156" and "Alfa 156", "Renault 5" and "R5"... well, you may be right on that point.
