In the cold light of day, I wasn't wholly happy with attempt no 1 so between snoozes, I built the second one. Much better although the photo doesn't do it justice, no 1 on the Left, no 2 on the right

Brian, If you fancy a go have a look on the Roxey Mouldings website, there are well over 30 of these Southwark etches, for a whole variety of railway companies. I am sure you might find something that takes your fancy.
