Just for interest, I found the MicroMint version of

lens extension barrel. It had the card, original software and manual. It
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.
