In the dustjacket, Morley is hailed as a great connoisseur of Nortons. I am willing to believe him he is an enthusiast, but no more. I have seen many a very good  picture taken by Don Morley in the classic racing era, but his knowledge of Norton production models is very limited.

It is not the quality of the photos. It is the descriptions of what they supposedly show.

A yellow Fastback with some café racing goodies from various aftermarket sources fitted is still a Fastback Commando, and by no stretch of imagination a genuine Production Racer, of which only just over a hundred were built.

The aftermarket-cast-wheel fitted, aftermarket megaphone-equipped dualseat(!) JPN lookalike we know from various NOC calendars and Norton publications remains a standart Commando, modified with a JPN fairing, but not a genuine JPN Replica, of which only about 300 were produced, etc, etc.

Unfortunately, the author knows little about Norton production models and cares less. Even more unfortunate is that Norton enthusiasts take this misinformation and believe it- I know- I had several customers ask me about the "JPN megaphones" over the years!- and probably, in a worst-case scenario, try to recreate these freak motorcycles in their quest to restore "back to original", or give a genuine one a miss because "it does not look like the one in Morleys book".

There are better picture books about, if a picture book is what you want.
