The Great Western Railway made tousands of benches by combining three cast iron feet with wooden planks. Over the years the castings changed to reflect new logos and occasionally they have become mixed up as benches are repaired. This example on platform 3 at Exeter St Davids has a pair of GWR 'shirtbutton' logos either side of a later British Railways (Western) casting.
