Fantasy Miniature Identification - Big Old Metal Orcs and Ratmen

[Belgian]

Stumbled upon these fantasy metal miniatures and can't find the manufacturer of these miniatures. The shown orc and ratmen miniatures are quite chunky and are cast in metal, some come with plastic bases others with cast metal bases (marked with the word figs). The other miniature is some kind of slender fantasy or scifi female warrior/ demon. Don't think the shown packaging is original but it's possible. Would somebody have any idea who made these miniatures and have some more information about them?

Nobody?

I'm tempted to say the ratmen are citadel skaven, the rest have got me stumped.

My guess is that the Ratmen are Heartbreaker. 

The Orcs could be from the old Canadian Enigma Miniatures. This is not the same Enigma Miniatures that exists now. They specialized in Warhammer and WH40K style figures, and used solid metal bases like those, instead of plastic slottabases. They got into legal trouble with GW and went out of business in the late 1990's.

The ratmen definitely look like Heartbreaker rather than citadel

Could the orcs be Alternative Armies? They did solid metal bases for a while, but I only ever saw the figures in boxes rather than blisters...

Could the Orcs be Excalibur Miniatures?

Thanks for the comments, have much more information for research now.

Will hopefully find them now on Stuff of Legends or similar sites.
