Theoretic proof:
The set 7755 was released between 1983-84. The following variants of motor were
released in between the following dates:
Type 1 bb12va: 1980-about the end of 1980
Type 2 bb12vb: (at least) 6th week 1981 until 24th week 1981
Type 3 bb12vb: 27th week 1981 until 1989
Type 4 bb12Vc: mid 1988 until 1993
Therefore the set 7755 came with ONLY type 3 bb12vb.
Proof using images of sealed or MISB sets: Bricklink store BLuxe generously provided
me photos of his sealed set. The image number 1 is taken from a sealed set and
the images number 2 and 3 taken from a MIBS set.
