6602A not even perm 3 in the first place.
6601C replaces 975M
6602A replaces 987D
8641Z replaces 1971S
So are you implying that 8641Z appeared together as the same
time 6601C started appearing on Sv 3 in replacement of the Mk4s?
Idk about you, but I certainly didn't observe that trend. I only
see 6601C 6602A 6603Y keep sticking to Sv 3 in the same period
those Mk4s from Sv 3 disappeared.
And what I saw was that it was only after 8641Z appeared
consistently on Sv 3 that I see 6602A consistently on Sv 39
too.
