More photos from the same event - just as they have been scanned - will separate later.
Norm has indicated he will scan them separately when he has time !!.
Article and map of the track from Graham Woods - Graham has a large number of programmes and articles on 1960's motor racing - he had the George Lawton 100/6 and Cooper photo posted on the Austin Healey thread among others I have " borrowed ".
Allan Dick of Autonews and Classic Driver and other publications noted that he had only ever seen 3 or 4 photos from the Napier Races.
According to a comment the road used are much the same today.
