View Full Version : What is it? Really?
Look at this wooden thingy, with a magnifying glass, on eBay: 280245546036 (The auction has ended, so you must log in).
The seller claims that it is a viewer for plates, but is it really? If you put a plate in it and close the lid, I suspect you can't see much...

There's a grooved bit that holds the plate up-right, see top left photo, and a simple viewing lens. It's probably a cheap viewer for lantern slides.

Why would you want to close the lid? It has a slot to hold a plate parallel to the magnifying glass as far as i can see.
ah Ian beat me to the punch there :)

I'm 2 hrs ahead of you Heather, it's not so early in the morning :D
Ah! I didn't notice the slot.

I bet its a graphoscope. See the following link.

It is indeed a graphoscope. I have one, a more sophisticated model which in addition to the large magnifying glass has below it two viewing lenses. Its purpose was to view stereo photographs in a collection of medical textbook plates. The plate holder moves back and forth for focusing; the magnifying glass enlarges the accompanying text.
