1913-14 Ford Coil Box. The 1915 to 1922 boxes were similar except for the shape of the top and top cover, which were more slanted to clear the cowl section. The 1917 to 1925 lids were made of three pieces instead of the one-piece stamping of the box shown here.

Starter-equipped cars (1919-1925) used the same basic box but without the switch.
