Hi I'm hoping someone could ID these items. One is a wild heerbrug prism ring, maybe some kind of vertical illumination beam splitter for stereo microscope?
The other is an old leitz box with some knobs with a small set screw inside, most are heavily rusted. Looks like something is missing in the middle, maybe some kind of metrology test kit? Hoping we can determine they are worthless so I can trash them and keep the box

Yes, Zeiss made a similar (almost identical) device for their stereo models. It screws to the lower ring, and you direct your incident lamp to shine at the prism, which then re-directs it down to the object.
So it is really a simple (and therefore cheap) and unobtrusive means of axial illumination. Useful for getting the light into crevices, especially with minerals I believe.

I get it now! Shame my box doesn't look like yours.R_REISENER wrote:
Hello. Here is a photo of the same accessory that I keep on my Orthoplan Pol.
Your box is missing a special slide manipulator that accepts point counting rings. The rings attach to the knurled x-y manipulators, and provide detent click stops at various spacings.
& to Perl, I shall never doubt you again!
thanks all
