During that time he has made a detailed and thorough review of all denominations. Hundreds of new varieties have been added to both 2013 and 2014 last edition catalogues. He was one of the three panel members who were responsible for the challenging task of reviewing all shades within the Kangaroo and KGV catalogues.John's study and strength has been the constant varieties, os perforations and overprints, coil perforations and gums, but in particular thin paper varieties. His thin paper research for the last 30 years has led to more than two dozen new listings. His greatest find was the 2/- Kangaroo 2nd wmk thin paper which was listed for the first time in 1994. This led to many more important finds which are now part of BW listings.John has been a member of PSC (Canberra)for the last 45 years.
