I have seen that rooster label on stuff that I knew was Seguso. The first two weights have cane clusters like some Seguso weights that I have. I have a weight with the identical canes as the red one. Fratelli Toso makes canes that are very similar but theirs tend to be more precise.
The last paperweight is a mystery to me.
My guess on age would be perhaps 50s but I am not certain. I think the rooster is an older label.
