If you had a clue about the rear wheel bearings on the originals and Kirkhams, you would understand there is no simple "adjustment" that can be done. The bearings are shimed to a specific clearance and pre-load during a rebuild. It is best to entirely remove the rear components and do a rebuild on the bench, not the car.
The picture is correct for a loose rear wheel bearing on a Kirkham, be afraid, be very afraid.
