 Française de Rome, 1991. p.69 dates M756's consulate to 44 AD (or 40 AD). 
Eck, W.: "Miscellanea prosopographica", in ZPE Bd. 42, 1981 p.252 dates M756's consulate after 38 AD.
Hillebrand: Vigintivirat (2006) p.156-157 (§60 [Mussi]dius T.f. [Poll]ianus), p.184-185 (§27 T.Mussidius Pollianus M756), p.219 (§1 T. Mussidius M755)
Klein: Sicilien und Sardinien (1878) p.94-95 (§27  L. Mussidius M754 suggest that the procos of Sicilia RE1 could be the same as the monetalis RE3.
That RE1 was an arval is only based on a coin image, which could easily refer to something else. 
Pflaum: Province de Narbonnaise (1978) p.6-7 (§5 T.Mussidius Pollianus M756)
Szramkiewicz: Gouverneurs Vol.2  (1972) p.419-420 (RE1 and RE4)
Tortotiello: Fasti Consolari di Claudio (2004) p.529-532 (§43 T. Mussidius Pollianus M756 with stemma p.532 adding a son to M756)
Wiseman: New Men (1971) p.243 (§266 = RE1, §267 = RE2, §268 = RE3; he prefers the reading "Polliano patri" for RE2, followed below, 
since his initial post of IIII vir viarum is unlikely for the son of a consul.)
