Vintage Blue Stained Glass Kaleidoscope

Description

This is a vintage kaleidescope about which I know nothing.
I remember buying it about 25-30 years ago....it was not inexpensive....but that's all I remember.
It is blue stained glass, and it measures 8 inches long (not including the 2 spinning kaleidescope parts)
It has been on display and totally neglected since about a week after I purchased it.
