Canada 713v And 716iii "Raised Eyebroe" Variety - Help Needed

I am having trouble identifying this variety from the two illustrations in Unitrade (2021) as copied below, which I don't find oarticularly helpful:

My first question: Unlistrade lists the plate bock price for these as corner blocks of 4 without inscription, so did these not appear on "true" plate blocks? If the answer is yes, then the whole issue goes away as I have, to this point only checked plate blocks - an easy route as Unitrade generally lists the positions of varieties on a sheet.
I did, however, find this half PB which looked a bit positive for the raised eyebrow syndrome - pictured below with a blow up of the relevant parts:


The upper stamp in position 1 has a wider eyebrow which appears to start closer to the bridge of the Queen's nose which bears comparison with Unitrade's image for 713v. And to be honest, Unitrade's image for 716iii looks very close to the lower stamp (Position 11) in my example which, to my eye, looks typical of the normal stamp.

Help would be appreciated in pointing me towards a better picture of this variety.

My Canadian Philatelic E.F.O.s Darnell 3rd Edition from 2005 identifes a 'bushy' eyebrow version of this 14c stamp. It seems to come in three different states. ie booklets too. They do not us Scotts numbers though which is a pain...

Hi:

This is not an 'easy to see' variety on these stamps. As noted earlier, it really is more of a bushy eyebrow variety, rather than a 'raised' one. It occurs in position 1 on one of the press sheet panes, and was on the master grey ink plate so is found on all three values (clearly it wasn't changed / altered between the different press / value runs). It is basically a thickening of the greyer area above the eye that normally creates the appearance of an eyebrow.

I have attached a few scans of my copies - hopefully these will help (the one close-up was done at 600dpi, the other at 1200dpi, but I'm not sure what 'shrinking' the files to meet the website requirements will do to their resolution).

Thanks for both of your responses.

paddle_more: Could you post images of the various states of this variety? As for multiple number systems, this is something I've had to live with for the past 70 years as an Australian collector. Stanley Gibbons for run-of-the mill and ACSC for varieties.

ModCanSpecialist: Many thanks for your images. Even the Unitrade illustrations make sense to me now.
