That's interesting. I used to have two binocular microscopes. Both Victorian. One by Dancer, the other by Watson another London maker. They had fantastic lens quality. With polarisers.
They are beautiful instruments.
I also had loads of slides from The Challenger Expedition and micro photos of horrific battles from WW1.
I sold them at Christies, had a clear out !
I used a stereo microscope in Switzerland when adjusting horrible pallet stones. A job I hope to never have to do again !
