I was able to find the manual page for this on line, so that link is on
the auction page - very nice, very huge - I wonder what its original
application was - anyone got a Mitutoyo catalog from about 1980? Can you
look up 252-372 micrometer head and tell me what it was supposed to be
used for? Just curious.

It goes on a optical camparator like this one:

thanks - that's it all right, and the counters make sense, run to one edge,
zero the counter, then run to the other edge and get reading - do the same
on the reference with the other counter?
