The result of more than six years of hard work by Doug Sayles, Volume 2 of the new ‘BNAPS Catalogue of Canadian Military Mail Markings’ is a complete reworking and updating of the previous catalogues published by the late W.J. Bailey and E.R. Toop (B&T). The reworking consists of a completely new numbering system built around keeping cancellations from individual military locations (by era or type) in a single group, and ordering them by marking shape and size. Each new catalogue number is cross referenced to a B&T number if one existed, and in the Appendices there is a reverse cross reference from B&T numbers to the new ‘BNAPS’ numbers.The spiral binding and heavy paper used in the Sayles’ catalogue are intended to allow collectors to use it to record and annotate their holdings and, with luck, find new and previously unreported items. The military postal markings of the World War II era formed the largest part of the B&T catalogues. All cancellations, both those previously recorded and the more than 400 new cancellations unknown to or unseen by B&T, have been reproduced in excellent illustrations. Volume 1, covering military activity in Canada from the 1800s through 1935, will follow the style and format of Volumes 2 and 3.
