I have had these old Servitor models since they were released sometime around 1989 I think. At least one is a Bob Olley sculpt, if not all of them.
They were painted way back then, but they were pretty bad so they got the Nitromorse treatment and repainted.
I saw Sho3boxes Servitors some time ago and I really liked the whole Borg style and was tempted to give the grey scheme a bit of a go, but they would not have fitted with the rest of the starship crew I am working on.
So I went for a more human skin tone. I will have to
rip off borrow Sho3boxes scheme another time…
