vintage c1900 "" Negretti & Zambra"" Stereoscopic / Verascopio Viewfinder This beautiful stereoscopic viewer or verascopio"" Negretti & Zambra"" is in the state it was found. The wooden body has acquired a beautiful color depth and patina over the years. No cracks or chips, but scratches and scuffs expected in this age viewer. The transparency support brass is present and sides inside and outside well. I tried to show the state in photographs. Glass lenses have no scratches or fungus and bottom glass plate is not damaged, but would benefit from a cleaning. The hinge of the front works well and is secure. When the wooden handle ebonised unwinds, the lenses extend and retract smoothly. Supports lenses are not damaged. In the back there is an ivory plaque applied to"" Negretti & Zambra"" which remains clear and legible.
