More serious and more enduring is his collection of postage stamps. Both his brother and sister had started collections of stamps but lost interest so Malcolm absorbed theirs into his own collection. Initially he collected stamps from all over the world but this became too much to manage and afford so he stopped collecting but kept them as they were. He eventually settled on collecting only British stamps, not including any colonies. In adulthood, he completed the collection by obtaining examples of every stamp issued in Great Britain, both mint and used, then augmented it by finding variants. The stamps are kept in date order in albums or stock books and, from the year 2000, a separate album was required for each year's issues. Separate individual collections were made of first day covers, stamp books and prestige books. Another special collections was made up of Victorian 1d reds. Postmarks, frankings and preprinted labels were accumulated and stored but were never formally sorted or presented.

 
Currency

Malcolm also had a collection of coins and paper currency which, as with the stamps, he absorbed those of his brother and sister. He had built up a good collection prior to the decimalisation of the British currency but sold off many of the larger denomination silver coins when money was tight for running the housekeeping. A tin full of foreign coins had been given to him by his great aunt Evelyn, many of which were from the British Empire. He was also given some Roman coins by another relative. At school he had been a founder member of the numismatic society and had been given some coins by his housemaster and society president, Mr Atkinson.

 
Cheese dishes

When living in the cottage in Dorset, Malcolm started collecting cheese dishes, being interested in the wide variety of patterns. Once having moved house, there was no place for them so he sold them off.

 
Railwayana

With his interest in Railways, he collected many related items such as tickets, luggage labels, paperwork and artefacts, the latter being shown in the railwayana section on his railways website. He also collected model trains to run on his model railway layouts.

 
Maps

Malcolm had an interest in maps from an early age, probably starting with those inside the cover of the Swallows and Amazons books. Ordnance Survey maps were of the most intense interest to him and he built up a good collection from different periods. He also accumulated some of the large scale County Maps which had preceded the Ordnance Survey. In connection with his travels around the country, Malcolm had kept all the various street maps that he had purchased to find his way about and they covered most counties in Britain.

 
Records

Malcolm's collection of records and CD's reflected his broad interest in music. It started with 78 rmp vinyl records of current pop music in the late 1950's then moving on to Skiffle and Rock and Roll. His first LP was Bill Haley and the Comets Rock around the Clock. During his last years at school, whilst already collecting some of the more popular classical pieces, he was introduced to Jazz, fistly Traditional then Modern, but he lost interest in the latter as it became too extreme for him. He next took a liking to World Music of a variety of styles including Reggae, Blue Grass and some Pacific Island traditional tunes. Whilst working in West Africa, Malcolm came across Soucous music which he took to immediately and from there he explored other African music cultures. After his retirement, Malcolm and his wife Brenda followed Cajun music, Appelation and Celtic. Malcolm's collection of recordings cover all of the styles listed here plus a few others.

 
Genealogy

Malcolm's interest in his family history started when he was about forty years old with a midshipman's chest inherited through his mother's family. The chest contained an amount of memorabilia which his mother had accumulated so he decided to study it. He quickly found a fascination for the subject and set out to research more detail and write it up for the benefit of his wider family. He had the benefit of travelling throughout the country for his work so took the opportunity to visit places of interest in the process. The project grew rapidly and became his nominated legacy for the future family and he became the keeper of the family archive. He created a website in order to share the information and also to attract information from others. He also produced a series of books on aspects of different branches of his more immediate family.
