Description "Stereoscope" Page 208 Made by Mattey.
"The 25 slide tray holding a set of views is marked "Nain, The french word for dwarf. The tray fits into a metal carrier which can be slid back and forth by a lever at the lower rightside of the housing. Serrated edges on two metal strips lock the tray into position. The viewer is then tipped up and the particular slide falls into place in the viewer. It is then dumped back into the tray which is moved to the next desired number."
