Welcome sewhatforu,
We like pictures! Especially of a tangle free bobbin.
I have googled Amica before (in relationship to the below links) and noticed that Riccar, Vigorelli and Nelco are affiliated with the name Amica. Nelco was an importer that trademarked the name here in US about 1965.
I'm guessing you have read
Nelco Amica
Red Orange..Yep.
Vigorrelli ZZ/A Robot
I'm wondering if your machine is like any of the above. I'd still like to see the 3000 in person.
