Gary,

Based on the timeline I previously noted: Gary "discovers" Johnson in the spring / summer of 1962, it takes Johnson a minimum of 6 months to come up to speed and baby dots being introduced in late '62 or early '63

1. I don't think Gary was in error on his timing to discover Johnson.
2. I don't think it took any less than 6 months for Johnson to get up to speed from scratch (As a sheathmaker).
3. IMO the only possibility that the window opened up enough for Johnson to make a significant number of brown button sheaths is that the timing of the baby dot introduction that Gaddis mentions in his book is wrong, and the actual introduction was sometime later.

best,
