1922 Corona 3 (Apothecary) + Tripod
This Corona 3 is very special. First, it has an apothecary keyboard—which was offered to pharmacists and physicians. It also has a label holder to help with typing pill bottle labels. In addition, it has a rest key to let the right pinky finger rest while touch typing. Also photographed is a Corona 3 tripod, which is itself a very rare accessory.
