Yes, I saw that article.
The street Stornello bikes were also interesting. Guzzi has made a bunch of models that are little-known, especially in the US.
Having a NFalcone, I've read about these obscure Guzzi bikes for a while now and I've had the treat of seeing them in the Guzzi museum at Mandello dL.
Anyone interested can pick up a Guzzi history book and read all about them. Going back to 1921 is a long time.
Among later bikes, the Stornello, Lodola, Zigolo, Dingo, Cardellino and other models, four-stroke and two-stroke, came from this historic factory.
