Good grief, buy a frickin magnifying glass then.
If you want to believe it's a "K" and has been changed, go right ahead. The problem is that the "original" being shown here is at such a low resolution that it's impossible to tell if it's a "K" or an "E". They look the same at that resolution. Zooming in doesn't help to improve a low resolution original. There must have been thousands of people on that thread yesterday poring over the original on Orly's site. All saw an "E.F." and a # 4,7044.
I see no modification between the two pictures posted here. Simply a higher resolution version that has clearer text.
