Description

Mirroscope
The Mirroscope is an opaque projector known as an episcope, and also referred as a magic lantern. The two electric light bulbs (inside) which illuminate the object to be projected. Usually this object would be a postcard, news clipping, a photo, or other printed matter, but objects such as coins or leaves could also be projected. The light is reflected through the lens, and the image is projected onto a wall or screen.
Many earlier models were six side but that design created too much heat and the updated 'modern' ones have a bowed front.
This an improved model (likely made around 1918), with the addition of the two heat stacks directly above the light bulbs, designed to allow the heat to escape while preventing light from entering. Focus is achieved by moving the telescoping lens tube in or out.
I was presently surprised that this unit still works when plugged (at great risk of shock but not so much as a spark) in and actually has a fantastic ability to project an enlarged image on to a wall or screen.  It has some blemishes but is really in fair good shape.
The projector is complete with nothing missing.  The electrical has been taped and should be replaced, it worked brilliantly.  It was designed so you could show one item while loading the next and then slide it into place.  The slide on this projector works perfectly.
