Canadian Perforations

Take a look at these Scott 776-779 "Ice Vessels" stamps.
Need verification on my measurements..If I am incorrect, let me know.
Check a few for me if you get a chance.{ have others to post }.

Robert

Measure the horizontal width - from the middle of the hole most left to the middle of the hole most right: should be about 40mm?!

Count the number of teeth - 26?!

Gauge = (20 times the number of teeth ) divide by ( the width in mm )


This goes for ALL comb perforations

Are we back onto this again Robert?

As Galeoptix has pointed out in his reply, and as I have told you probably a dozen times in the past (in private e-mails), use the formula method to confirm your reading (which is wrong, by the way).

The correct measurement (and as noted in the Unitrade) is 13.0 x 13.3

Please, please, please use the formula method Robert before posting anymore of these.

Here is a 707 block from the 1977-1982 " Floral Definitives" which has a time stamp on stamp of 1977. The perforation measurement has been written up as 12.0 x 12.5...issued April.22.1977

They are another set of 1979-1983 " Floral Definitives" which has a perforation measurement of 13.0 x 13.3...Issued August.16.1979

My 1977 bock measures 13.0 x 13.3

Am I missing some thing..???

Robert

And thanks again UnitradeEditor for the kind words.
BTW, can you remove a name from the front of the Catalouge..Thank you

Re: 1977 date

Robert: same answer as the last time you 'pointed' this out...

The date is the copyright date of the image, not the date of issue. This image first appeared in 1977 (Scott 707), as perf 12.0 x 12.5 (and also as important, printed by CBN using lithography).

Your example appeared in 1979, as perf 13.0 x 13.3 (Scott 782 - the one item you did not highlight in your images). And also as important, printed by BABN using photogravure.

The printing method is more importance of a difference as the perforation for these stamps, and in fact, is an easier method to use to differentiate the two printings.

Bottom line, the copyright date should not be used to identify the second printing of this stamp.

Also bottom line, read all of the catalogue.
