Back in the 1980s, the Morgan Club Deutschland and its sections issued several cog wheel style badges, made of plastic, with two threads at the rear, to allow fitting it to a grille.
 
These are hollow at the rear and light of weight, even though they have a section of 95mm, which is 20mm more than the most metal badges.
 
The badge available has been part of a big badge collection and was never used on a car, so it is still as new.
