Vtg 1987 Dyed Birch Miniature Dioptric Scope - The Dragonfly - Multi-Prism Lens

Description

Here is "The Dragonfly" dyed birch and brass miniature multi-prism lens dioptric scope from 1987.
The Dragonfly
The concept of this odd and curious dioptric scope was first experimented with in George Washington's time.  Our multi-prism lens gives the observer 24 upright images of anything viewed.  This miniature instrument's bell-shaped casing (copyrighted) is made of layers of dyed birch which are laminated together with a special (patented) method.  It should be noted, if you have a keen eye, that this device has been signed and dated on the brass lens retainer ring.  You will find that there is an endless fascination to the multiple witness of simultaneous upright images . . . once perhaps, unique only to a dragonfly.
