Sorry, no earlier Matrixes. I write what I know, I'm not gonna bs about guns I've never dealt with. I also don't consider DM3's to be in the "Dye gun family" at this point. If the Dm4 is the grandfather, then I guess the DM3 is the wacky ancestor you tell everyone you are related to, or something like that.
I suggest reading through Speedy's FAQ, it discusses the earlier trixes.
