Does anyone have any literature, or sources about the 1948 Gaggia Classica commercial machine? I'm interested in technical 'specs and how it operates. I like reading about early Gaggia history.
Thanks! Steve Knox

You should look for patents CH262232A, FR986124A, BE489053A, AT179620 or DE938804C. These are not so different from the original patent («Robinetto per macchine da caffé espresso», number IT 432321, from August 8th 1947) from which I own a copy I had to pay for.
