I happened to stumble upon the Italian State Archive (Archivio centrale della stato) and with some advanced squirreling you can find the archives of The Ministero D'Agricoltura, Industria e Commercio. The ministry was responsible for the trademarks and they have their archive digitalized. The way these are presented varies, but usually it consists of the image and on a separate page a description or notes. Since this determines which trademarks were introduced at what date, it will help us with dating hats. Unless there is something special to note, I'll just post the images by brand and by year.
As some have pointed out, there is a risk of these trademarks getting buried in their respective brands threads. In this thread I'll gather them all for future reference. There are still quite a few more than what has been posted this far.
