And I’m an idiot – when I found this a few months ago I attempted to download it, but all my attempts failed . . . so I thought. But it turns out I got it! My apologies, people (especially @joseph ).
Since the meshes (two versions, look identical to me but they’re different filesizes) are in .off format (which Blender can’t import) I’ve used an online converter to get them into .ply format (which it can). Also made a pdf of its AIM@SHAPE page from the Google cache, now included in the zipfile. Not that it’s a particularly good mesh by today’s standards, but if anybody’s interested I’ve now got it up on my Dropbox here.
