Yes, the rear lights (Carello or Altissimo) were used on the GT 1300 Junior Zagato and the Berlina 1750 had them from 1967. These lights are also used on more exotic Italian cars.
The hart on the front could originate from a Duetto. But then the centre would have been cut out. It isn't as shiny, maybe a 'homemade' item?
The top curvature of the rear screen looks a bit like the rearscreen of a Porsche 911?? I haven't got a clue about the bumpers.
