i know grantye was working on an andromeda mod but it doesn't seem to have gone anywhere

nope sorry thats the eternal vigilance, you got the right series though

Here's a textured pic from in-game:

Sorry--not up on the Andromeda ships.  He has two custom models in the game.

Here's the link in his mod about the project with some images (scroll down a little).

Was that image above a Sins model?  What's it out of?

Hmmm.  Not sure what's up there.  He has a much more primitive cruiser class in his mod other than the one I posted before the last there--which you have identified as not the Andromeda.  

The picture above is his shot from in-game so somewhere he has the model.

Maybe it's been laid over the mesh of an existing model and uses its name.

Just FYI, unless its something releatively simple or easily available, you pretty much need to make the models yourself or at least trade favors with someone who can. There aren't a lot of good modellers around and many of them have their own mods they work on. Now you maybe able to find a suitable model on the internet somewhere (as I guess this is from a scifi series), but I highly doubt anyone is  going to come along and do a complicated model for you when they can put their talents to something they care more about.

Sure doesn't.  Now someone make my mod for me too darn it.

I'd be willing to give it a try but I have a real life and it might be six months before you saw a finished and untextured model.
