Thanks for reviewing the models!!
I'll fix my models.
They are built several years ago (before joining this community) and prepared for OMR recently, so some errors may exist.
Regarding part 3062, I think there were both molds (3062a and 3062b) exist concurrently in those years (around 1978).
As I (born in 1983 and begun playing LEGO system bricks in 1986) haven't seen a real-life 3062a, the transition should be rather fast.
Thus, I have modeled them with 3062b, except the sets before 1977 (pre-minifig era).
