This quote is where the author seems to reach the conclusion they want, that is Gorton being the Proto-Indo-European of these drafting letterforms:

> Each of these reappearances made small changes to the shapes of some letters. Leroy’s ampersand was a departure from Gorton’s. Others softened the middle of the digit 3, and Wrico got rid of its distinctive shape altogether. Sometimes the tail of the Q got straightened, the other times K cleaned up. Punctuation – commas, quotes, question marks – was almost always redone. But even without hunting down the proof confirming the purchase of a Gorton’s pantograph or a Leroy template set as a starting point, the lineage of its lines was obvious. (The remixes riffed off of Gorton Condensed or the normal, squareish edition… and at times both. The extended version – not that popular to begin with – was often skipped.)
