I need a 400K badge...
tcar, that badge is a factory 356 badge. Reproductions are available here
http://www.356sales.com/badge.html
Although I believe that originally the badge celebrated mileage with the original motor and gearbox.
In the first thread I saw on this topic,

the poster (Paul491) said that they were going to approach the factory for permission to reproduce...
