Leader of the pack

After a drizzly morning, late in the afternoon the sun came out in all its glory. As we walked down to the Harbour Master for a pre supper beer in the sun a pack of middle aged bikers trooped past us headed by a three wheeler sports car. A few minutes later we saw them all parking up and heading for the chippy. The three wheeler did look glorious in the sunshine and was obviously the owners pride and joy. 
Does anyone know what make it is?
