Just to let you all know, there is a short film called "Sunbeam Rapier brings you a European holiday" on Monday 9th December at 10:40 on the Talking Pictures channel which is channel 81 on Freeview. I don't know anything else about it but I'm looking forward to watching!
Unless it was specifically edited, it certainly highlights what a bright and 'modern' colour scheme the Rapier wore in comparison to what seemed the norm back then...
