This is the badge designed for the first All Morgans' Day event, held at Blenheim Palace, back in 2016, organised by the Roadster 100 Register.
 
Just over 100 copies were made of all varieties of this large oval badge, designed by Tcherek Kamstra.
 
The last copy available is unnumbered. It is simply excellent.
 
I haven't seen another one for sale since the event. If you want the badge, please act swiftly.
