Yet more work to do, I think there's more than enough here to demonstrate that there are letters and numbers within the torn piece although still somewhat faded in appearance. It needs to be borne in mind that some kind of special technique was use to insert these letters and numbers and whether that was the Ink H method discussed in earlier posts or perhaps some kind of chemical, I cannot be sure.
One thing for certain is that the torn piece is still in existence and could be/should be tested for the presence of chemicals. If the ink H method was used then the paper would need to be immersed in a strong bleach solution to remove the inks leaving the pencil marks.
