1.T stands for Tachymeter, hence the 1163 T which we call Siffert has a Tachy bezel.
2.The Viceroy autavia came 1972, many cases or maybe all ?! cases around this period were marked V, which is logic as Viceroy autavias made the volumes explode. Later there was a second case supplier brought in to cope with demand.
To answer your question: the red pointed hands were used for V and the rarer more expensive MH version.
3.Viceroys had 1,2,3,4..12 dials, the earlier ones with steel hands, steel hands black inserts would be MH versions

The eraly Autavias are very interesting and you are raising a very interesting topic which needs more attention or even a careful written publication in one of the Heuer friendly magazines. A lot of details are unexplored.
