Re: rear wheel bearing seals, 22nd series custom 8, 1949

There is an inner seal between the bearing and differential to keep oil contained inside the case. An outer seal held in a retainer on the front side of the backing plate is supposed to contain the bearing grease.
Any oil or grease that gets past the seals is directed to a guard which is essentially an enclosed space where any captured oil can drip down and exit thru a hole at the bottom of the guard. That oil is directed to the rear side of the backing plate away from any brake components or lining.
Here is an illustration from the parts book with the position of the backing plate in the layout noted. There is a photo of the outer seal and retainer assy on ScottG's post about his 55 which has essentially the same layout and axle seal detail as your 49.
