Alfa Romeo 1900 Sprint with a retractable roof

[Djetset]

Here's another mystery to me.  It's clearly an Alfa Romeo 1900, reported in a Swiss magazine around 1959-60, but does anyone know who built this coupe/cabriolet conversion please?  Thanks.

The car is equipped with a Marelli movable roof, but according to Salvetti (in the book Curiosalfa) it's not known who added it to the car, maybe Touring itself...

Ah, thank you Iluvatar, I thought it might be Touring itself as well.  May be we will never know!
