For reference on your last point, the $402,817 weekly payroll would have been anywhere from $3,854,603 to $10,590,425, depending on whether that "peak of production" was closer to the plant's 1956 bankruptcy or the plant's 1825 opening respectively. Source
That would have been 1918, since production for Model of 1917s effectively ended in December, 1918, due to the end of the war.
