This is "Mini Escape", a wonderful little brass kaleidoscope by Karl Schilling. This scope has a 3-mirror system and a high powered magnifying lens. The scope has a dry, turning end, end lit object chamber that includes lampworked glass. Also, the object chamber is accessible so that you can change the items in the object chamber and add your own. This scope measures 5-1/4"L x 7/8" in diameter and it comes with the wooden stand pictured.
