The above perforator no. 67529 is produced by the father of our joint passion J. Sloper & Co Ltd in London. As seen in the photos below, it can perforate 7 characters at a time, these 7 are interchangeable. The perforator has been found in South Africa for approx. 35 years ago, along with a similar one, that was sold to a collector in Slovenie, where this “sister” is today is unknown.
What it has been used for, I can only guess, but most likely not stamps. Most of the Slopers produced perforators were for purposes other than postal.
Who the user has been is also not known, as the protocols and accounting books that are intact after World War II and in the custody of The Perfin Society stop at No. 66813 ordered January 20, 1938 and shipped 5 days later on January 25, 1938 according to Roy Gault.
To time this perforator, Roy has made the following calculation. The first mentioned in the accounting book is Nr. 66472 shipped February 4, 1937, it tells us that 341 pieces have been produced in 355 days, giving 0.96 / day. If we assume that Sloper has produced linear, then No. 67529 will be produced December 13, 1939. Of course, that is a guess but the year 1939 will probably be realistic.
I have 26 different matrices, 24 of them you can see here, the last two are defective. As can be seen, 4 characters upside down, digit 2 + 3 are smaller.

I also chose to use the machine to perforate stamps with MM for the few letters I send. To date, 5 letters have all been sent with old marks and CHRISTMAS 2019, first time December 2019. Any readers of this bulletin who could be interested in in the perfin “MM” can ask for a letter with perforated Danish stamp, only by pay the postal cost.

This perforator can also be inspected at the annual general meeting for Danish Perfin Collectors’ Club March 14th 2020 in Nyborg. Details will be announced at www.perfin.dk
