hmmm. I think there are, but they're in .max format.  Vanishing Point would be a possiblity, though I'm fairly certain they don't have this particular model (but I'd love to be wrong..;)

Try doing a search with Mig 25, and .obj as 2 search words. Or model, mesh, Poser, etc., as the 2nd search word.

I wish I'd said that.. The Staircase Wit
