Sorting my 3-cent Small Queens - A Beginners Guide

All Froggies scans have disappeared.

I can see no images...Have we been hacked?

Thanks Jack,
Gee, don't know what happened there, all my images disappeared.
All is OK now.
We have had humid thundery weather here, maybe a wireless thing.


For the record, the math,  (taking into consideration inaccurate small scan)
Top Perf = 12.94
side perf =12.09

Not needed Brian,  the scan is the fly in the ointment.
With the math, one has to "count the teeth"  (The pointy bits)
One lines up the left hand border of the design, and see where the nearest top tooth lies
sometimes the border gives half a tooth, other times lies in the valley.

A large 600dpi scan gives the most accurate reading, you can line up the teeth accurately.
With Froggies scan, too much is left for guessing.

Example 
If there were 10.1/2 teeth across the top design the perf would be 12.35
If there were 11 teeth across    the perf would be 12.94    (a big difference,  added to that Frogs perfs have cut off some of the design, but not much in my opinion)
Cheers


 

The hole in your math theory is you must "judge" rather the design lines up with half a tooth,quarter of a valley or any where in between which allows for wide berth of error.Big difference between quarter and two thirds in a math equation.That is if I understand that it is what your using.

Done with this one and moving on.THANKS Brian.Still have to tackle the ones and twos as well. I was joking with my Mom and oldest sister just yesterday over the turkey dinner,about how Mom had taught us to read a perf. gauge well before jr. high.That makes like fifty years of looking at the dots.Time flies when you're having fun.

Jack you're right about that, another blessing in my life.A family of collectors is probably not a common thing.The unfortunate thing is it's only two generations as of now.Maybe one of our kids will get the bug soon?? Has anyone else here had a parent as a philatelist ?? I try to educate my youngest whats what and how to spot things of interest but do so with caution.I don't want to scare her off it can be overwhelming this little hobby.

Here is some good information on perforations of the small queens:

Well, this tread contains lots of useful information on the 3c (37 /41). Since perf represent the measurement of the number of "holes" over a 20 mm distance, I am thinking all we need is a 20 mm transparent ruler to superimpose over a scan. The real question is how to do that using standard scanning tools/software? Any advice woud be welcome, as I have over 300 of those orange stamps to sort out....

gillesletimbre,

I took the liberty of correcting your image upload. You want to copy/paste the "IMG" link from PB into your post.

Please remember that once you upload an image, you can't delete it from or move it within your PB account or it will disappear from your forum post.

Admittedly this is an area of my Canadian collection I've only tickled. I really need to go back in and sort them properly and redo some album pages.
But as an aside, I'd suggest checking out the November 2014 issue of Gibbons Stamp Monthly magazine. There was a terrific article about the small queens, outlining the history of the issue, and some of the varieties.

Brian, what is that fantastic caliper tool?

Outstanding!!

Thanks very much for sharing this!!

(You don't happen to have a recommendation for a virtual perforation gauge, do you?)

I believe I have a copy of the November GSM. If that is the case and someone would like it, just shout and it will be in the next post. If more than one, then I'll put the names in a hat and draw one.
Let me see if I can find it first ! [It will have to be tomorrow, the wife is sleeping ]

FOUND IT !
Anyone interested in the magazine just holler. Going free for one lucky [?] punter !
