Lookup at Kew - 89th Regiment

[Arundel]

I don't know how big an ask this is but if anyone is going to Kew would it be possible to look up the movement of the 89th Regiment for 1851. The reference is WO 12/9138 and WO 12/9139. They were in Ireland and I have managed to get an idea of their movements for the other years I needed from the museum in Armagh (wonderful place). I would arrange for copies to be made for me through the NA but I don't know what size of a thing it is and if it would cost be a fortune. Any help would be most appreciated.
