Anyone have an idea when the change from 6 screw coils to 4 screw coils is?

Just fined in an article by Ron Patterson. It should be 1916-1917 period.

If the encyclopedia is correct, then the change started in 5/14/1915 so the 16 model for sure.

Read Page 32 here...http://www.aeroelectric.com/Reference_D ... System.pdf

That spells out the change orders, but there is some complication when considering Ford vs. K-W production. There are a lot of tongue and groove, 6-screw coils, for example, and that doesn't match up with the change orders.
