K2F Mags.

Some K2F magnetos have an earth brush at the drive end. Some have one in the contact breaker. My automatic 1956 one on the Dommy has a brush at the drive end. My manual one (no date label) has a drive-end one, and shows witness marks indicating that the contact breaker had one as well, but the c/b is missing

I have both a ATD mag. and a manual mag. On the contact breaker plate the upright stem that pivots the heel is hollow on the back side. The manual mag. has a spring loaded brush in it. The ATD mag. has nothing in there. Both give good sparks so what is that all about?
