Want to see an ultra-rare camera prototype that's going to be worth serious bank? The fact that it's a Leica camera probably comes as no surprise, but the fact that it's die-cast probably does.
According to Leica Rumors this was the first ever die-cast Leica camera prototype, which was built around 1933 / 1934. And this rarity represents the earliest experimental version of what we know later would become the Leica IIIc.
