For many years, there had been 3 recorded unused blocks from Plate 3.
- The Armitage block of 8
- A block of 4 which used to be attached to the Armitage block
- Another block of 4.
Not too many years ago, a fourth block surfaced at a smaller auction company.
This block was 89-90/99-100L3 showing the centerline, at least on pos 100L.
Well, we are now back to 3 known unused blocks.
Note this 100L3 in Siegel sale 1232, lot 1069:https://siegelauctions.com/lots.php...232-lot-1069
I have a scan of the 4th (former) block, and I can say that I'm positive that this 100L3 came from it, and, obviously destroyed the entire block for this single graded stamp.
I would post the scan, but I do not have permission to post the one I was given.
If I can find the original auction listing scan, I will share it. Might have been Dutch Country? Not sure. A number of years back.
