From memory the base of the Ebay weight looks very similar from the base of my example. This is from memory only as I am away from home. Still, I am fairly sure that the weight sold on Ebay is indeed a 3 Fiori weight. The canes look right to me. In all likelihood, 3 Fiori used labels at some point but had moved to acid-etched marks when I bought my example.
