Not quite that simple...pinky and I are not discussing whether the aircraft in the pic is an A or a C but whether Mac Lee had an A or a C. He owned an A and also operated a B at one stage.
Talair had C402s (short nose/round windows/tip tanks) and 402As (long nose/round windows/tip tanks).
C402Bs had long nose/square windows/tip tanks and the 402Cs were essentially, outwardly at least, a B with wet wings.
