1 Wild M3 Coaxial illuminator. Asking $50 plus shipping.
I recently got my hands on an old Wild M3 (it was supposed to be an M3z, but oh well). I'm currently working on a stand for it which will be its own little thread, but it came with a coaxial illuminator which I don't need. In theory it should be compatible with the Wild M8 and the whole Leica M/Mz series (onwards from the M3 that is, not including the M5). I am not 100% sure of this as I haven't tested it myself, though since the heads are compatible it kind of follows. It had never been opened when I got it (Wild screws apparently often have something like loctite on them which requires a lot of force the first time they're unscrewed), but there was a slight film on the prisms which I cleaned off. Not sure how it got there since the lenses were fine? Either way it's clean and ready to use. I haven't been able to actually test the light, though it was sold to me as working and looks to be in very good physical shape.
I would have needed it for id work on beetles. Reflections are a real problem with them sometimes, especially since these are freshwater taxa and therefore in ethanol on a petri dish.
