The kit is essentially a George Vth which just happens to have splasher parts parts to 'convert' it into a superheated Precursor . The Georges did have, in some cases, the sandbox fitted below the footplate but later batches had them moved above i.e. within the extended splasher, the Precursors however always had them below footplate level with the filler and operating linkage above on the footplate. As said before the spashers on the Precursors/Superheated P's were fitted much further in than on the George, more like a Jumbo 2-4-0, resulting in a much wider footplate step in front of them.
