"Sylvia" is a wooden parlor kaleidoscope by Bob Tupa that features an emphasis on natural materials.  This scope has a 2-mirror system with first surface mirrors.  There is a 3 diopter lens.  The scope body is of Figured Walnut and Curly Maple and the finish is a combination of boiled linseed oil and shellac.  The exposed brass components are Laquer protected.  The turret has a ball bearing mechanism for smooth operation.  The turret is also designed to have an open side.  This allows for lighting from the side or from the end to give a variety of viewing experiences.  This scope comes with two interchangeable cast acrylic object cells and a wooden holder for the extra cell.  Each cell is fluid-filled.  One cell has a black background and contains shavings of walnut, curly maple, mahogany, ebony, bacote, paduk, maple seeds, white pine needles and brass wire.  The second cell is completely clear and contains colorful lampworked glass, beads, dichroic glass and wire and this cell can be backed with either white, black or opaque background.  The object cells are held in place by a steam bent wood component of walnut.  This allows for easy substitution of the extra object case and/or background disks.  The turned base is recessed to minimize instability and rocking and felt pads are on the bottom to protect the surfaces upon which the scope may be placed.  This scope is signed by the artist, named and dated (2018) and it measures 17"T x 9"W at the base and 12-1/2"L.
