Bausch & Lomb optical comparator mounted to a stereo dial zoom microscope with boom stand. Each eyepiece can adjust magnification independently if you lift the central zoom knob. All of the optics look clean and free of major scratches, fungus etc. All the knobs lock down as they should, everything moves and adjusts and focuses as intended. This is a working optical comparator, you should be able to install it then get to work.
These are very hard to find on the used market in any condition, don't pass this one up. Please note that Canada Post is quite expensive relative to other countries' postal services. I will happily provide more photos if there's anything specific you want to see or want me to test.
