I would like to find detail information, history, pictures of Fontanini Nativity scenes and figures, Euromarchi and other makers of Nativity figurines/scenes and related products?

I began collecting Fontanini figures last year and I would like to get detail information as to the mediums used when they began, dates of changes to diferent mediums ect. I have a member booklet that has given me some information but I want much more details specially before 1983. Where can I find pictures of all items made?
I also came across somewhere that Euromarchi is made by a Fontanini son of Simonetti is this true? How can I get more information on this maker also?
There are also several famous sculptors of nativity figurines although not often heard in the US. How can I get information on these other makers?
Thank you for your help!
