Circa 1920s STEREOSETTE visual examination instrument
This is a collapsible instrument that folds down to fit neatly into the original wooden box that also accommodates the instruction booklets and 18 visual testing plates.
Good working condition with minimal evidence of wear or use to equipment, the lenses are clearly unmarked.
The testing cards are a little worn at the edges, commensurate with card of this vintage, but are clear to use in the plate-holder for the preliminary testing of eyesight.
Box dimensions: 395 x 225 x 155mm
