One of microsoft's first mice had a particularly fat butt, it was later toned down into a less fat butt. IIRC Both were known as "Intellimouse" but it's the earlier fatter one I care about.
I'm looking for someone who has the FAT butt version and can SCAN it. Just the external shape, even if the buttons and details are inaccurate. I want an accurate scan of the entire shape, specifically the fat butt as it relates to the rest of the chassis.
If you have one and can take a series of orthographic projection style photos that might also be useful. But I suspect its more likely that someone would have a 3d scanner than be able to actually produce useful photographic orthos.
