I assume any camera described as 'untested', especially regarding the light meter, means it's dead. Mercury cell CdS and Selenium meters do not age well, even if their owners bother to convert them to the proper voltage. Avoiding the subject is many sellers' way out of having to admit the thing is junk.
Something that never fails to amuse me, is the condition of screw thread Leica lenses for which substantial sums of money are asked. There's one Youtube video extolling the virtues of Leica lenses, and you can barely see the second element for a dark cloud of fog. Plenty on ebay have glass that looks like the bottom of a dirty milk bottle, and their owners describe them as in good, or even excellent condition.
