Alan Runfeldt runs a 1930s era print shop in Berkeley Heights, New Jersey, USA. As well as traditional letterpress printing Alan rescues, restores and passes on old letterpress equipment such Kelsey Excelsior Platen Presses, Chandler & Price Platen Presses and Vandercook & Challenge Proof presses. He also collects, catalogs, uses and some times passes on fonts of hand-set foundry type and wood type as well as the cases and cabinets to keep them in.
I don’t think this press is in Alan’s collection, his website says the press is in Philadelphia. I had to include the picture, though, it’s got to be the oldest litho press I’ve seen.
