yes maybe it is as you say, that the color of the fork is original and also that of the rear stays in dark green. However, in Paola Pezzo's photo you can see a little of the fork which has a black bow and gold fork sliders. The photo is from 1993 because Paola is wearing the world champion jersey.
I can ask Paola Pezzo directly, who lives 100 km from my house, if she still has her Procaliber lei from 1993, or does she have any photos
