I've had this for some time in my cupboard and had no idea it was never released. I knew it was a prototype but only yesterday I googled what it was and I was really surprised to find out that it was never released and that wikipedia said "some rare ones come in a silver case; although they are marked "NOT FOR SALE", some were sold on eBay for more than €2,000." Mine isn't that valuable I'm sure, as it has suffered a bit (read below). I'm in a really bad place financially right now and I could really use some money. So I might sell it if anyone is interested in it.

The screws holding the battery case are missing, and so is the original battery and I'm testing it with a slightly too long battery from some lumia phone. Original screen protector is still on tho, and so is the camera lense protector plastic. There is 2 cut holes in the battery case for some reason, and some rubbery substance in one of them.
