Age related observation ....
Pat Howson, a friend and previous editor for the X/9OCUK, had a pukka replica prototipo named 'Strawberries and Custard'. I saw it many times over the years and the Abarth script is vertical, not italicized. Added to which, I have, somewhere, a set of black and white photos from the team's visit to the UK as well as their factory - showing the same.
In fact the FIAT ABARTH lettering is about 5-10% shy of the required thickness but I ran out of fonts to compare the original script with.
STOP PRESS: New font found with better match as standard - Olivia Antique Black - see updated image in earlier posting
