All I have done is copy the original picture posted in Post # 1 on this thread and put it in PhotoShop and adjusted the contrast and brightness so what we are looking at is a bit clearer. I then enlarged the document and cropped the area of interest.
It sure looks like a K.F. to me. 
Yes, it always looked clear to me - a defined K. And if the excuse has been that the original E was distorted due to too much compression or whatever then why wasn’t most of the rest of the document also distorted? Is there now, anywhere a K document left and does anyone know if the paper copy of IT exists separately from the paper one that Orly has submitted with the E?
It looks a lower case K (probably typo).
