For your consideration, here is a Vintage Toy Steven Kaleidoscope, made by the Steven Manufacturing Company of St. Louis, MO.  It is 8 7/8 inches long.  It has wear and tarnish on it.  There is some missing printing on the turning part of it.  It works, but it is kind of hazy when looking through it.  May be best as a display piece.  Item pictured is the actual item up for sale and comes from a non-smoking household.  (310.89v-.9hc)
