I just found a copy of the same re-entry as you (with some horrible perf too) I am not sure either it is the item ''N'' as there is some major doubling in STAGE and in CENTS (espescially the ''S'')(re entry clear) instead of ''MARK'' as there is on item N.
Also the item ''N'' is suppose to have a third inner vignette line right side of the queen, while ours have only 2. Sound pretty clear it is not item ''N''
Here my crappy copy (will post better scan once I receive it)
Well, now, look at this found on eBay
with a VGG CERT claiming our stamp, are, #27IV DOUBLE PRINT TO RIGHT... I have big doubt about this http://www.ebay.ca/itm/Canada-27iv-...AOSwOyJX5Vsq
If it is, then JACK POT! hehe but I doubt. I once contacted G.archer about this one and he said he wasn't there when they approved this Cert and it is certainly not the double print. (As in the double print we can clearly see twice the stamp)
I checked the Duckworth book and all other documentation and found nothing about it.
We may claim this is a Very strong or either a Major re-entry as a Big Portion of the stamp is doubled, the whole right side (from the middle)
