I've seen Ferro weights that had a bunch of flowers over a puleguso ground.
I am in the process of learning the Ferro&Lazzarini look. I have some weights That I'm close to positive they are Ferro&Lazzarini. One (the red spiral) I have seen with the Ferro label. Another I identified because I saw some of the same canes in known Ferro weights. I have also seen that red sticker that's on one of mine on stuff I knew was Ferro. All of these are the same size and shape which makes me think they are Ferro. I have also seen the flowers and puleguso in this shape. Other makers have their own distinctive 'egg' shapes.
