Scotland Bill

My Lords, perhaps my noble and learned friend can help me on the use of air weapons. Would it be possible for there to be two sets of regulations north and south of the border? In those regulations, would it be possible to prohibit the use of a weapon from England, say, in Scotland where it does not have to be licensed, whereas in England it has to be licensed? Would it be possible for the Scottish Government, within regulations, to make an order that that weapon could not be brought into Scotland and used?
