Collection of Pre-Decimal to Decimal Navigators to Date

Here is a set of pre-decimal navigators, minus the cream paper 10/- specimen (very difficult to find, I've been searching for one for the past 3½ years), and a set of decimal navigators. There are other shades both in the pre-decimal and decimal series which are not in my collection, these shades have not been located but when any are located I'll add them to the collection.
