Thanks
Thanks very much for all your comments except for Lord Ullswater. It looks as if Halton – who I think designed the Goblin asked for the engine back from Malcolm Campbell because he wasn’t happy with him using it!
I think in the process of polishing it I have rubbed off what was left of the chrome and gone through to the brass – I suppose it is possible to get things re-chromed.
I have since discovered this picture showing a similar plate mounted in position.
