I found this, and am not really interested in that magnification but maybe someone is or has comments. It seems quite old, designed to mount a camera on that top piece, maybe up to medium format?
Vickers Lab Microscope Great condition $500.00 ( CASH ONLY PLEASE)
Includes Vickers 100 watt power unit.
Binocular and Monocular lens's = X10
Camera is not included
It must be some version of a 'Photoplan', another version sold on ebay recently for $200 as-is untested:
