This simple elegant scope is more than first meets the eye…Expanded two- mirror system, which uses a triangle of mirrors, but one side is blacked out, making a single circular design surrounded by black. Depending on the angle of the mirrors as the 2 wheels rotate the image can have a 4,5,6, all the way up to over 100 points of design! All in this 9”L 1 ½ “ diameter brass tube. Two 3” diameter wheels: one of artist made millefiore glass pieces, and one of stained glass.
