Optician's drawer unit

Large drawer unit from an optician. It dates from the 1950s. It has 25 drawers of various sizes, with lovely chrome brass knobs. And a door that leads to 6 sliding shelves, which were once used to display glasses. The unit has been repainted several times; it is currently red and black, with the red being slightly less bright than in the photos in reality. Some signs of wear related to time and use.
