Using the Intertype stick attachment - setting large display lines from the matrix cabinet
The Intertype composing stick attachment includes a special setting stick, similar to a composing stick, for easy hand assembling of lines of matrixes and spacebands, and a special hinged first elevator head for quick insertion and withdrawal of hand-set matrix and spaceband lines.
