The Scott 192 King George V has a variety called "Broken E" known as Scott 192i...If you have a suspected Scott 192i, but a cancel is covering it, there is a way to verify whether or not it is the variety....I took a couple of my blocks and posted one below (position 87).

Now I used software to put a fictitious cancel over 2 stamps..Can you tell which one is the Scott 192i, left or right one..?

If the 'E" is hidden by a cancel but you can still see the rest of the letters of the word "postage" then there is a way to know if it is a true Scott 192i or not. There is a constant "dot" on the letter "G" on all Scott 192i stamps...See picture below and if you see it, you can be sure it is a true Scott 192i variety...See blow ups of "postage".

Just for your information
