Revised. Thomas Gravemaker sent these photos of a German-made Grafix proof press used during a recent four day event at Officina Tipografica Novepunti in Besano, Italy. The fourth photo below shows a cylinder trip assembly similar to a Vandercook Universal (1958-76) or a No. 4 (1935-1960). Some Grafix models have an adjustable press bed. The manufacturer Haas & Kellhofer Maschenenfabrik, which began in 1924, was separated from the controlling company in 1975. The successor company, HKS Filtration-Technology GmbH, guesses that production might have started around 1957 and stopped in 1972-73. Like FAG and Korrex, few are known in North America.
