Very interesting and they are accurate measurements..Any comments..?

Robert, on stamps this old I never worry about 0.1 as far as perforation goes. Could just be Father Time messing with the paper?
What I did notice is that you quit flyspecking! Just kidding of course, but your scan looks like the left "5" says .5 instead?

A little trivia on this very nice stamp---Design thought to be by R.Ostrander Smith from a photo by Russell of London.

ya peter you could be right..looking a little too close.

Thanks rdavid for that bio information.

Even though the 0.1 (1/10) perforation difference or less is not always thought of as important, to specialists it is if it is consistent, constant and proven. An example occurs in the Canada Large Queens where earlier perforations were around 11.93 mostly and later ones were around 12.02 mostly which were found by Stephen J. Menich in his Large Queen perforation study article. See: BNA Topics, Vol. 50,No. 5, Fourth Quarter 1993, Whole No. 457. There are other such instances too which make a difference in distinguishing perforation changes.

"After the B.A.B.N.Co. moved to Montreal, it was found that 83% of the stamps examined carried perf. 12 (12.0 + .02 = 12.02 corrected) on at least one side, during the Montreal Printing period (Table 3). After the B.A.B.N.Co. again moved, back to Ottawa, it was found that 96% of the stamps examined carried perf 12 on at least one side during the Second Ottawa Printing period (Table 3).

The long use and consistent quality of the perf. 12 value suggests that a dedicated perforating wheel with a metric equivalent gauge close to 12.02 was added to perforate most of the Large Queen stamps of the Montreal and Second Ottawa printings, and some of the First Ottawa printings."

The existence of this 12 perforation which lies between Kiusalas 66 (11.93) and Kiusalas 65 (12.11) as 65.5 (12.02) somehow has brought Kiusalas into question in this instance.

wert: See page 25 in "The Canadian Stamp Perforation Change of 1962" booklet for a listing of some perforating wheels (192, 193) used.

ok jogil..if I can find it or even still have it.
