Jacques, Congratulations on buying the Anniversary camera that DVD had. It is certainly an authentic example and I was going to buy it my self, even though I already have one, because I wanted the very rare box. But when I found that the box did not come with it, I didn't buy it because I have one already.
Vlad, DVDTech is not the only one supplying them. I bought mine from a seller in Novosibirsk several years ago and other sellers have had them too. There are also fakes of this camera and it is small variations in the engraving style that will allow the fakes to be differentiated from the authentic examples. It is hard for me to describe these variations, but they can be seen easily when a real and a fake are shown side by side in photos. Also, from the different examples that I have seen during the last five years, I would guess that only about 25% are fakes and 75% authentic.
When I find a good photo of a fake example, I will post it in the WIKI along with photos of a real example and then will explain the differences. It is a good idea for any one interested in this camera to look at the box on the DVD site and copy the photo of it (for reference only). As you can see, when you look at this box, there is no doubt that it is authentic!
