Well Hugh..  As you know I'm always working on U.S. Scott 231 for the last 15 years I have over 50 thousand of them. But I need more. I will conclude research this December. Then write a book on all my new findings. The book will contain the progression of the broken hat, New Plate numbers containing broken hats and frame lines A whole new chart of right frame line breaks double broken hat on same stamp cracked plates every where and so on. I might look at progression frame lines but who knows . A stamp wroth collecting and researching. I seams most research was about the hat and types and a lower right frame line breaks. But there are more Upper right frame line breaks and Hat break combos never recorded. Different hat type breaks and the second hat break plus a double hat break on same stamp.
