There is also a 90 page introduction expanding on the ‘Handbook of British Perfins’ first published by John Nelson in 1967, but branching out into Joseph Sloper’s family tree and his Victorian workforce, the alphabets that were used, errors, illustrated covers, and lots more and a spreadsheet itemising all the plate numbers against each of the dies.

Roy Gault

Second Edition

2024

Wartime provisional perfins were produced by J. Sloper & Co. after their premises were bombed in 1941, using combinations of perfin dies to produce the required letterings.


In addition to the fully illustrated catalogue, a spreadsheet listing all 807 provisional perfins and scans of the original ledgers from J. Sloper & Co. that provided much of the information in the catalogue are included.   Also included are scans of all the other post-WWII Sloper ledgers which are currently on the Perfin Society website.



A Catalogue of GB Perfins found on Stamps from Coils

Second Edition

The make-up and identification of the ‘official’ rolls also appears at the back of the catalogue. 


A basic introduction to ‘Coil Stamps’ has been presented that is relevant to Perfins rather than say, Vending Machines. This is followed by the details for each Perfin Die as per ‘The New Illustrated Catalogue of Great British perfins’, but organised under the various categories numbered 2 to 9 below. An overall index is included at the back to help locate any particular Perfin.
