What i have been able to find out is that these are modern and possibly Italian. I know they are at least 20 years old as that is how long they were in storage when I bought the unit. There is a signature on the bottom but I have no idea how to identify such a thing. I am very very new at this and so any feedback is greatly appreciated. One thing that I am hoping to find out is what is the best way to research items without spending hours and hours ?
