Through a long-time friend, I have been in touch with one of ‘Pa’ Norton’s grand-daughters and she has recently written to advise that Mr. H S Norton was almost certainly her uncle Henry Spencer Norton who would have been in his early twenties when he took delivery of the bike. He was the youngest-but-one son of J L N and at the time, the family owned and lived in a house in Brandwood Road.
But there is another slightly intriguing fact to emerge: Henry’s daughter (my contact’s cousin) has been under the impression all these years that her father never actually owned a Norton so perhaps the cause of the bursting crankcases put him off them for life!
