My old friend , George Madis, said when it came to Winchesters " there're no rules".
Winchester came to Madis for info, when he was alive.
Madis would stay in bed , most mornings, Patty would bring him coffee or breakfast. He would answer letters, faxes, etc.

Barrels of parts would show up in assembly , and they were used to put guns together.
It did not have to be at the end of a production run.
