It's not an oversight. The truth of the matter is that I'm not a particularly skilled modeller. Getting an exact likeness of an object is a little beyond me right now as my knowledge of the various 3d modelling construction methods is currently a little limited. I think if I had more NURBS experience, I probably could nail it.

I thought that maybe the person requesting the file would be satisfied with a freebie that was a reasonably close facsimile.

I've tweaked the handset again based on your observations. The shape still isn't dead-on. I think I'd have to start the whole thing from scratch to really get it, but I think the tweak still resulted in an improvement over the last version. I think I could be tinkering with this thing for weeks. :)
