E. These are the lubrication points for the delay mechanism. For every speed from 25 to
150, this mechanism delays the shutter blades to ensure that the shutter blades remain
open for the appropriate amount of time. If your shutter blades do not close properly
when set to 25 speed but work well on 150 speed, the problem most likely lies here.
Unlike in the pre-war Shutter, some of these spindles are not easily accessible because
the tops are blocked by a metal plate. To lubricate these spindles, force the lubricant in
from the side of the spindle.
F. This lever rides on a cam on the Face Plate. When you rotate the Face Plate to set the
shutter speed to B(ulb) or T(ime), this lever sets the mechanism in A to the proper
position.
G. This lever also rides on a cam on the Face Plate. It controls the shutter speed from 25
to 150.
