Every perfin known on GB stamps (as at 1st January 2022) is illustrated and details of the user, dates and place of use and which stamps are known with that perfin are given where known.

The complete catalogue runs to over 3,400 pages.

This catalogue is only available as part of the "Sloper 154" USB memory stick detailed above.

Updates to the Gault-2 catalogue are published every two months.

First Edition

2024
Digital publication, 449 pages 

A detailed listing of all 1,383 Different Dies (using the tried and tested format in ‘Gault-2’), along with additional historical details concerning the user (where known) accompanied by numerous images adding to the story.  

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.  

Second Edition

2024
Digital publication, 385 pages 

A much expanded and updated edition of the Sloper Wartime Provisionals catalogue which first appeared in 1992 and won a silver medal in the Philatelic Literature section of the 1995 Autumn Stampex Exhibition held in London.

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.

Second Edition

2022
Digital publication, 160 pages 

The objective is to illustrate all known perfin dies used on Great British Postage Stamps coming from Coils, also referred to as ‘Rolls’. This includes the ‘unofficial’ hand-made rolls of stamps (from c1910), as well as the official rolls produced by the Post Office from August 1918. 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.
