The AT4, when you look at the front of it, spins counter clockwise.

This AT4 was installed on a 1917 Henderson and worked in that application just fine, before being replaced with a the correct Berling N44.

The K.J. needs clockwise rotation from its magneto, when looking at it from the front.

The American Bosch AT4 is listed as standard ignition on e.g. Case farm tractors, circa 1923.
Plus on other tractors stationary engines etc.
A closer view of the patent numbers may narrow it down.

American Bosch manufactured a large range, in huge numbers, so most models are not exactly scarce. Farmers being farmers fitted them to anything that needed a magneto...

Which direction does it spin ?
