Vintage Stereo Microscope Objectives - in wood box - 6x & 4x for Leitz Wetzlar??
SHIPS TO USA ONLY.
This was from my father's estate and believed to fit an old Leitz Wetzlar Stereo microscope, or a Leitz Greenbough Stereo microscope.  I am not sure, but have included measurements.  The optics look good other than minor dust.  They don't have a brand written on them but do have some numbers in the groove, same numbers on both looks like "57", which is likely the total measurement including the knob on the side, as that measures approx. 57.5mm with a micrometer.
PLEASE SEE PICS for details and measurements.
Please see my other items for some interesting finds. I am adding more items every day or so.  I will be listing more microscope objectives and oculars soon too!
