I feel lucky to have bought many of my cabriolet unique pieces early in the rebuilding process, as some are no longer easily obtained. While my car is not at all an attempt at restoration, I always felt it important to keep the top as close to right as I could. An early photo ( from 1930) showed the car did not have the brown edge trim common to most other cabriolets. The paint is based on the Andalucite Blue formula, but a bit lighter and less reddish. Andalucite Blue was the original color of my car when new.
