This is an untested vintage Russian microscope Not sure how these work so unable to see if it’s usable The main body doesn’t go up or down when you twist the two knobs either side, it might be jammed or I’m missing something Comes with some extras and a nice wooden carry case with working lock and key I’m selling this as parts or not working Please study photos carefully
