I have other bits of history to mention, seems to be the right place to do so.
First, on the Cornuta model: there is a patent existing but for design and model (it was deposited on October 20th 1947, number IT27438; you'll find it on my episode 23
). From what I've recently discovered this model is one of the first horizontal boiler machine (La Marzocco had a patent back in 1939 but it is really not sure they actually build these machine with the beginning of the war). Well, almost the first one: it is Cimbali who really commercialized the very first horizontal boiler machine with the Ala model (in early 1947) and later with the Gioiello.
My last, but not least discovery is about a well known picture : the Giuseppe Cimbali picture, dated close to 1912 (in front of his first commercial address). It is not as famous as the 1906 Bezzera picture above, but it should...
If you look carefully to the coffee machines in his workshop, there's a Bezzera Gigante at the back (very first model from 1901 patent, no other known picture to my knowledge) and... what I believe to be the first (and maybe only) picture of a A. Moriondo machine (inventor of the express machine, patent dated 1884), in front.
A piece of history that was waiting to be discovered.
You'll find all the details on the episode 24 I just posted
