I have no idea what these are and was hoping someone in this forum might be able to give me a clue. They were donated to my astro club and I got assigned the job of getting them sold. I would really appreciate it if someone could tell me what a reasonable amount to list them for would be. (Not trying to maximize dollars coming back, I just want to get them sold and into a new home.)
I suspect they're for a microscope, since both say "10x" on them. The top of the Leitz one rotates up about a 1/4 inch; assume that's for zoom or something.
Let me know if you need better pictures, CN website would only let me upload low-res versions.
