The following 12 characters could be perforated.
Now, the keen eye of several readers will see that the first character (#) is similar to the FIG 01 registered in the Catalog of Danish Company Perforations.
It turns out that they are 100% identical and the catalog committee has chosen to note that the very few stamps found with Fig 01 are perforated with a corresponding check perforator from B F. Commings & Co. Which company, if any? have used such a perforator to perhaps both cancel checks and secure their postage stamps, is constantly in the uncertain.
The perforator will be available for inspection at this year’s general assembly and proofs can be obtained on the same occasion.
