    Just for interest, I found the MicroMint version of

 sat on a shelf in my lab, forgotten,for years, until I got into
 classiccmping, and *then* I realized exactly what it was.  I have a pic of
 it that I could send if someone needs visual regognition. 
 
It was, indeed, C mount.
BUt, ... if you were to use that much extension on a lens, do you know
what you would be in focus for?   IF it were a 25mm focal length, and you
were to ADD 25mm extension in addition to what would be needed for
infinity focus, then it would then be focused for 2 inches away, and give
you 1:1 size of image:subject.  With a 12mm lens, it would provide
substantial magnification.

    The device now resides in Germany somewhere, deep in
a secret warehouse,
 gaurded by Dobermans.  No one really knows what's in there, save one
 deranged German Engineer, but he will not talk about it much. 
I had one of the Micromint ones, until about a year ago.  It was never
anywhere near any Apple products.
I don't know where it is now - Sellam probably has it.
