I had absolutely no idea what it was. Being on the top of the dashboard gave me a clue that it was something for the driver and it looks kind of electrical, but what a strange shape – what the devil is it?
I contacted Charles Vyse, author of ‘Survivor’, a fantastic book about the rebuild and maintenance of a RR 20/25. Charles said “John, it’s an early cigarette lighter”. Thanks Charles!
I had discounted my thought that it was a cigar/cigarette lighter because the shape just didn’t really seem correct! Oh well, I don’t smoke. Interesting none the less.
