Hi MineSweeper, welcome!
If you would like to post the numbers here I will add them to the list.
Please let me know if they are on the lower or upper margin of the selvedge, if there is any mark of the front of the booklet, light, medium or dark, if there is any Blue 1 or 2 also on the selvedge, and where in Canada (town, province) they are from.
Oh, look to see if the back of the stamps have any extra ink on them and let me know that also. And any other feature you may have noticed that we haven't. Thanks.
I have not called
Canada Post in Antigonish (Philatelic Centre) but I would imagine that they may just say, well, we have some booklets (if they have any) and we cannot distinguish between what you may get or not get from us.
I myself do not have any extra Blue 1's with numbers but perhaps others may. You do need 50 posts to buy, trade or sell on SCF here however. Or use the SCF email feature too.

I have been very lazy over the summer with these. I want to check out the size of left and right-hand selvedges to see if there is any differences or similarities (widths in millimetres), and also to have a look at the placement of the numbers, to see if there is any pattern there, regards to how high or low the numbers are placed on the selvedge (as per Timbres post above).
