It is quite likely that the actuator is stuck as well, and disconnecting the actuating rod and giving it a belt on the end may help. May not too, if the rollers are rusted in place.
Hitting the drum on opposite sides as I suggested, once free from the centre hole, this action will also tend to free it from the shoes, where a straight pull, such as you have if you undo the centre nut, will, if the shoes are stuck against the drum, tilt the shoes and make them grip more tightly. The hammer blows will shake them loose. (Hopefully)
