This book is intended for those who have a keen interest in perforation analysis. It is a guide to determining the perforation status of the line-engraved stamps of Great Britain which were perforated on the Napier machines. It provides a foundation to the subject, and focuses on demonstrations of analytical procedures involving the visual comparison of perforation characteristics. Essentially, the book identifies the perforation characteristics that differentiate between genuine and fake perforations. It also catalogues genuine and fake perforation varieties, and gives many examples of the four categories of perforation status, i.e. Genuine, Fake, Non-compliant, and Non-determinable. The subject matter of this book is a key element in expertising the perforations of these stamps.
