Stamp Perforations, Perforation Measurements And Perforators

Does anyone on here study stamp perforations, perforation measurements, perforation gauges and/or perforating machines, especially relating to U.S. and Canadian stamps?

Are you talking about Perfins in general, or just the machines that perforated them?

It's about the perforations as separations that separate stamps from each other rather than perfins.

Why does it have to be specifically about Canada and the US???

The knowledge about perforations is quite universal....

This is most quickest & easiest way to check the perforations on 1,000s of stamps at one time by using perfs to measure perfs.

The example is Australia King George V issues but it suits any issue.

The 2d Orange only issued as a comb perf 14. The 1s4d Blue does not line up so it is a comb perf 13.5

The perfs line up so the perf is perf 14.

Hope this has been helpful. KGV

Great pics and info once again John, AKA KGV. Thanks again.

jogil, I am becoming interested in perfs more now, despite my failing eyes, because of the modern concatenations (chain links) found in many modern stamps, specifically the Marine Life, Sweden / Canada 2010 for me.

Perforations have always eluded me as they were frustrating. It was easier to collect the pretty pictures and the shapes, large and small, and match them up.

Your book I wish I had though haven't investigated the price or availability yet. My library of reference material is so small seemingly. Always needs more stuff. Oh, and time to peruse it, ha.


How do you study the perfs/ Can you say without me buying your book or is it too detailed to convey here?

I do have a Instanta look-a-like from canada perf gauge and a plastic gauge for checking modern smaller coil perfs in detail. AAgaian, the time constraints.

Puzzler, I mostly look at the perforations on old stamps and compare them against the Kiusalas gauge to find a matching pattern. Also, the booklet "Early American Perforating Machines and Perforations" by W.S. Boggs is helpful and interesting for old stamps.

Thank you.

You're Welcome Puzzler. Regarding my booklet, some of the perforations shown and covered are hard to find when compared to the usual common ones so that it is important to know what and which ones to look for. That is why the booklet is important. Stamp issues with long printing runs have many different varieties and this specifically covers their perforations.

Here is something from my collection ,its on the pink card ,this will play with your head when your using a perforation gauge . [URL=http://s463.photobucket.com/user/stamp12345/media/bosnien.jpg.html"][/URL]
