It is unknown to me. The other canes in the weight would date it to the late 2nd quarter of 20th century, which may make research problematic due to the passage of time. My suspicion is that it is a happy circumstance. All Italian signature and date canes with which I am familiar are, how shall we say this, "quite obvious, and not subtle". They are "in your face" with the information. And since this one is not of that style, leads me to my conclusion.
