How can I buy this tachistoscope instrument for my research
While the tachioscope in our collection is not for sale, eBay is an excellent resource for finding old technology in good working condition.

I have one identical to this that I no longer have room for. It appears to work perfectly but I have no slides to truly test it.
You can build one yourself?
