Statement of the author
The Ur-Leica is a replica.
The last four objects are originals and fully functional.
Their fine mechanics and optics have perfectly withstood the time.
During their time of production they were way ahead of their competing products, if these even existed.
The top right picture was taken with the Leica from 1940.
