Well, now that you've explained it, it seems pretty obvious. Thanks.

Tom, the pistol rides along the rod to prevent the slug from turning when the
lead screw is turned. If the slug rotated with the lead screw, it would never
move into and out of the inductor. However, since the bore in the pistol and
the OD of the rod must provide some amount of clearance for easy
movement, there would be a small (very small) amount of deadband in
tuning when you changed tuning direction as the pistol moved from one side
to the other side of the rod. The wedge shaped little washer and the spring
work to provide a force that holds the pistol against one side of the rod
regardless of which way the lead screw is turned, hence no deadband.
At least I think that is what it's purpose is......maybe. :-)

I'm curious as to how that "backlash rod" functions, in fact, just what
its function is. I'm intrigued especially about the purpose of the
little wedge shaped piece that rides on the rod and butts up against the
pistol. Maybe you might enlighten me?
