The Baby Dragoon/Wells Fargo '49 Pocket models in .31; .36 cal Trapper models, Patersons, and the replica .36 and .44 snubbies are the only ones that I am aware of without loading levers. The Patersons, Trappers, and snubbies have a loading tool. The arbor on the '49s the appropriate size for loading the cylinders.
