I doubt a manual will be of that much help. The info shared above is very helpful though.

For reference, here's a link to what a slightly newer manual and repair manual looks like:
Astoria Argenta JUN SAE-1 Manuals - Does anyone have a PDF?

Looky here, one of Almico's myriad useful posts:Astoria Argenta SAE-1J

They've heard back from Italy. It is an Astoria Sonia. Discontinued for 20+ years and no other info. The gentleman here in America said it was a new one on him.

Names are important so this is excellent news and very nice of him to contact the manufacturer in Italy.
