Don't know what those are CBC. duct tape will do to get the spines out.
What they look like sub lente, parts?
Got a great deal on a new microscope myself a couple of years ago, its served me well ever since, mainly either for helping when I need to confirm a wild mushrooms identity before potentially eating it, or for my occasional microbiology/biotech oriented projects. Wish it had a camera mount, and measurement scale calibrated in microns, but that aside its pretty good all round. Got the option of fitting a dark-field condenser, but I'D have to buy one and as yet I've no need for it. The ebay seller was happy to understate the price for tax purposes too, never paid a penny in import duty. And threw n an oil immersion lens plus oil for really high-magnification.
