Historical information

This wooden board, which was used to make the system portable, served as a firm base needed to sustain puncture pressure when transcribing. The metal hinge held paper on the board, and a row of holes either side of the board held a frame in place, thereby ensuring that the lines of Braille were straight across the page.
