This antique vintage laboratory microscope glass slide box comes with a collection of glass slides. I can't see any microscopical preparations. Ideal for collectors of scientific instruments or those interested in the history of microscopes. Primarily of historic interest rather than for the contents. The case has scuffs and wear marks. There are some of the 100 slides missing. The slides have etchings on them to match up with the paper index, however I can't see any sample on the slides. I have included a picture of one of the slides. Most are similar.
