I agree. A few pictures for comparison here: http://www.hpmuseum.net/display_item.php?hw=275 The printers appear to be Data Products 2310 drum printers, also sold as the HP 2767A; photos: http://www.hpmuseum.net/display_item.php?hw=332 The ones in the original photo do not appear to be the HP versions, though, as there are no HP badges present under the operator panels. -- Dave
