Soprani Castello accordion

[John F Wilson]

I recently acquired this accordion in excellent shape, am trying to determine its age/manufacture date.
It's in a Geib case, also in great shape.
I've found good info on Geib (& Schaefer).
Is the Soprani the brand, or the model?
There was a Paulo Castello, and I've seen both Paulo, and Castello, models.

Is the Soprani the brand, or the model?

AFAIK, the badge indicates it's made by Settimio Soprani.
It's also pretty old, like sometime in the (late?) 1950s. Bellows pins, with the same head design as these, were already in use by Settimio Soprani during 1948/49.
Over the years there have been several different Soprani makers. (Originally, like yours, Italian: More recently, Chinese.)
So, Soprani is the maker and Castello could be the model.
I'd say it's a robust, mid-range instrument from "The golden age"!
