The Roadster 100 Register within the Morgan Sports Car Club twice organized All Morgans' Day at Blenheim Palace. Badges were produced for both occasions, to assist in the fundraising for Combat Stress. Both badges were designed by Tcherek Kamstra.
 
All badges were sold. It is now hard to find one. The 2018 badge features a three-wheeler and a four-wheeler, with the Blenheim crest of arms featuring prominently on top.
 
This is the second series of these badges. The variety remaining has got a black rim and red coloured Morgans. 
Solely 10 copies were made.  The badge is unused and thus excellent!
