Description
This is a vintage Cooke, Troughton & Simms M30195 microscope, manufactured in York, England and marked with Patent No. 467926. The microscope dates from the 1930s, and comes with its original lenses and eyepieces. No case is included.
All mechanical components appear to function normally. The focus controls, stage movements and adjustment knobs operate smoothly, and the optical pieces can be fitted together as intended.
However, the microscope is being sold as defective. When the instrument is fully assembled, it struggles to transmit enough light through the optical path, making it impossible to see an image through the eyepieces. All pieces work individually, so the issue is likely due to an internal obstruction, misalignment, or a problem with one of the lenses or prisms, but the exact source of the fault is unknown. No attempt has been made to dismantle or repair the internal optics.
This item is therefore offered for parts, restoration, or repair.
