Mating of two of my favorites:
The Leica IIIG and the Pentax 43mm f/1.9 Limited fitted for a Leica thread mount body, referred to as 'Pentax-L Special'. The lens was only made available in Japan.

I have always lusted over a Leica III. There is something so artful and beautiful about that body. And its use is so deliberate; you have to think about everything relating to the picture you are taking.
As for the lens, I have used the AF K mount version for years on my Pentax film and digital bodies and have found it to be as good, within the limits of its maximum aperture, as the four Leica normal lenses I own.
