I' not certain, but Leno may be referring to Dave Matson who built this Prince for Jay.Another very watchable video from Jay, but with a few inaccuracies, the Mini signalled the end for the production of Vincents? but the time lines do not match. Did the Prince really really an electric razor kit supplied? He makes reference to Stuart Jenkinson (I think) but does not actually name him, but states that the owner of a Prince purchased one new in 1955, kept it for 60 years and put around 100k miles on it, well as we all know, Stuart's achievements were far more impressive than a mere 100k miles.
I was wrong, this isn't the bike Matson built. I was surprised by the amount of inaccuracies Jay said, i.e. the spark advance lever, instead of the chokes. He's usually pretty savvy, but not this time.I' not certain, but Leno may be referring to Dave Matson who built this Prince for Jay.
