This catalogue was initially assumed to be 1966 as when it was obtained it had a 1966 price list inside. However, the clue to the date is on page 11! There are no model changes from 1964, there just seems to be a redesign of the presentation on the pages with “Vic the Viking”. A suggestion from Vic Davies perhaps? (Peter Bevan Sept 2022)
