Classic badge, in honour of the 35th anniversary of the Morgan Plus 8, issued by the Morgan Sports Car Club Holland in 2003, designed by Geoff van Beek.
 
The title 3.5 decennia refers to both the 3.5 litre Rover V8 engine, and the 3.5 decades the model had lasted then. The Plus 8 was then succeeded by the Roadster model, but the Morgan Plus 8 still has a special ring to enthusiasts.
 
As the badge is a virtually perfect copy of the 15" +8 rim, it is also known as the "wheel badge" 
 
Good copies are now hard to find. Few -unused- copies remaining. Priced to sell!
