Baur-type Convertible from Italy: The Autobianchi Bianchina Trasformable:

Thanks to Sicilia Classic Clubs for posting a pic of the 1958 Autobianchi Bianchina Trasformable, another example of a Baur-type convertible:  fixed windows, fixed B pillar, and removable/convertible roof.

Here are a few more examples.  We had never heard of this car before, so we are indebted to Sicilia Classic clubs for posting it!  Thank you!

The Autobianchi Bianchina is a minicar produced by the Italian automaker Autobianchi, based on the Fiat 500. It was available in various configurations: Berlina (saloon), Cabriolet (roadster), Trasformabile (convertible),Panoramica (station wagon), and Furgoncino (van). The car was presented to the public on 16 September 1957 at the Museum of Science and Technology in Milan...... Transformabile featured fixed B-pillar and partial roof, as the rest of the opening was covered with foldable fabric hood.
