I've googled high and low, peeped dozens of pictures of more or less common lenses, but I can't find any that would have such nipples on their back side.

Anyone have a clue?
Well I understand now, that this is maybe a wrong forum for these kind of questions. Anyway, if somebody happens to have same problem, I found out that it was Komura's own "Adaptall" type of arrangement, and it's called Uni-Auto. Those adapters are apparently harder to find than the lenses themselves.
