This record contains one Formstacker. The paper tag says "Museum," with the date 1990. It is a mechanism on a pedestal, with a bass plate. It has a paper feed and an adjustable wire rack on the inside, and another wire rack on top. There is a "lower tray" button, which presumably lowers the interior rack as paper is fed onto it.
