One example of this game from Europe and pictured here shows no bells inside its backbox while another example pictured here shows a bell mounted on the backbox wall and its '0-9 Match Unit' has a clapper for a second bell that has since gone missing. For more information about the absence of factory-installed bells in some EM games found in Europe, see the Notes for Bally's 1969 'Cosmos'.
