- Italian pipe blogger, Gusto Tobacco, did some fairly detailed original research into Ernesto Ossola and La Torre pipes, which is available here: Ernesto Ossola's tower: a story to remember. This is the Google translation, which leaves a bit to be desired, but it's readable. Contributors, it would be great to expand our article here on Pipedia based on this research. Please feel free to dive in and do that if you are interested.
