These are the miniatures which were released prior to the first edition of Warhammer 40K which were an influence; obvious candidates include Bob Naismith’s C100 Imperial Space Marines and the Judge Dredd miniatures which Citadel released.
Wondering what the various icons/symbols on the page mean? See the key here.
C100 Imperial Space Marines 
These guys were the first proper release of Space Marines, following the LE2 limited edition release. The eight of them were seen in the August 1986 Citadel Miniatures Mail Order Sheet. The November 1986 White Dwarf (#83) shows one in black and white and references Naismith’s “excellent hard line work” on the C100 range:
They have 1985 on the tab as the sculpt date.
2000AD
Not 100% on the date JD10/JD11 was released but I’m leaving it here.
