This one is on eBay since at least March 2008 and I think it's a fake. The speed dail is wrong, the shoe and some other details too, and the s/n is too long (only five digits seen normaly).
I think that it is a "custom manufactured camera". I have 5 that are identical and it varies in several details. I think that someone had a rangefinder cover and took a body and made a camera!
