Identification of an old Reichert stereo microscope

[Klaus Yde]

I have this old beaty of an old Reichert stereo microscope, which have served me well for several years - but now has been replaced by a newer zoom model. I has the number 242 647.

I specially liked that I could  search a petri dish for small protozoos without moving the dish. I havent seen any new stereo microscope with this ability.

Can anyone help me identify it? Or eventually help me with a link to a prospect or manual?

Kind regards
