Where did my plastic terminators come from?

I have plastic terminators that are one piece with clip on arms like they came out of a starter box. They are similar to the terminators in the black reach box, but crappier.

I thought they came from Space Hulk, but I recently saw some old Space Hulk terminators, and they don't look like those at all.

Where did these terminators come from?

They look like the ones in this ebay auction:

Thats the old 5 man plastic box set.

That it is, Marc.

I was surprised to find out they were actually a boxed set by themselves. They are of such low quality, even for older models, that I figured they must have come from a board game or something else.
