The day after the wintry mix, I started pulling the headstock apart
because the head of the 4th bolt holding it to the bed is inside.
The top half separated cleanly and I set it aside.
This was my first look at the gearing in there. Fairly
substantial. I fished the two halves of the wooden gizmo from the
sump at the bottom of the headstock. It acts as a brake on the
countershaft in the foreground when the middle headstock gearshift
lever is in the mid position. It split and fell off some time
ago. Its thoroughly impregnated with oil at this point.
Another view of the spindle gears.
