If it gets easier to do, I may just find a 26" three speed back rimIf the arm says it's Perry, I'll bet its Perry. That is not a hub I know anything about. I would clean it all up starting with the hub. Those bearing surfaces look trashed. Maybe its just old dirt and grease, If they are as bad as they look, you need a new shell, and since you are lacing the wheel you could replace the whole hub with some other brand if it is easier to get.
