I don't know if this nice kit was originally a Protar, but I can tell you that it was also sold by Revell, which I think is the original producer:

Here there are all the 3 Daytonas I have, that represent a part of the 29 plastic model kits I have still to build:
1/24 - Italeri - Ferrari 365 GTB Daytona coupé - Rosso Corsa 300/9, black interiors
1/24 - Italeri - Ferrari 365 GTB Daytona coupé racing - Rosso Corsa 300/9, black interiors
1/24 - Italeri - Ferrari 365 GTS Daytona spider - Rosso Corsa 300/9, black interiors
After watching this nice and clean build, I can't wait to build my Daytonas! However, I don't want to use bare metal foil for the window trims, and I am still wondering how to correctly reproduce the black air vent on the C pillar. I think I could leave it painted in chrome silver, rather than ruining everything painting it in semigloss black with a thin brush.
By the way, the color of this metallic blue Daytona should be
Blu Sera Metallico 504/C, right?
