I'm trying to write an "history" on computing machines used in my research institute before electronics. The institute where i work was founded in 1927 to study and apply computational methods. I've an article published in a 1941's newspaper with a photo showing a room of the institute and some computing machines. I'm not able to recognise one of these machine. Anybody can help me? You can see the photo at http://www.iac.rm.cnr.it/~celli/unknow.jpg I enlarged it as more as possible, but quality is the quality of a newspaper during WW2 thanks, Andrea
