Indian Plug (B)
This Indian spark plug was made by American Machine Co. of Eau Claire, Wisconsin. I include it with my Minnesota collection because it has a pipestone core. Pipestone is only found in Minnesota near Pipestone, Minnesota. This is a very early plug and quite rare. The name "Indian" is stamped in the base. This plug has a different base than the other Indian (A) spark plug and it is a bit unusual. This plug belongs to Chad Windham of Pendleton, Oregon and he sent the photos to me.
