I just
inherited a nice little collection of Canadian stamps. The books have been basically unopened since the early 1970's and everything is in good condition. I'm in the middle of documenting and photographing what I have, likely to facilitate a sale at some point. I've done enough to know that I'm not likely to get rich off of them, I know.
Documenting most of them is fine, but understanding the variety of colours, sizes and papers for Small Queens is further than I am willing to go at this time.
But there is one SQ that I haven't seen on any of the usual websites. It is a 3-cent Small Queen, but appears to be printed on paper that is the larger than any of the other Small Queens:

I know there is a variety of sizes, as evidenced by these two SQs:

But the one above at 25.5mm in height is larger than any of the others I've seen (the one in the comparison photo is 22mm, maybe 22.5mm)
I know even the SQ experts out there can't identify exactly which one this is without a perforation measurement and an accurate assessment of the colour.
Basically, I'm just looking for any information on this stamp. It is just another 3c SQ or should I continue to research this one?
