I'm in the process of editing a book of events that took place in Oxford from the 10th to the 20th century. The person who wrote the draft is dead so I can’t ask him this question.
There appears to be an abbreviation for “Knight” using an upper case, “K” followed by a lower case, “n” followed by a lower case “t” half a space above the “n” and I cant find such a “t” in symbols so can any help?

Do you mind posting an image of this "t" for clarification?

Oh so kind of like a subscript/superscript kind of thing?
