first of all the tag is gone but on the center section there is a good number c7awc the pinion housing is guarded, and there are three ribs. the housing is somewhat round not a hump. maybe this will help it does have the small bearings, with eleven inch by 2 inch drums. 4.50 bolt circle. yes the brakes are two inch not 2 and one quarter. thats where I'm confused. humbly john!
