There lies the problem. Whilst I am aware of the existance of a photo, unfortunately I don't have Mr Russells Wagon appendix.
So much time has been spent trawling through books with a Western bent to no avail.
Perhaps I will have to wait until some kind soul can advise meof the colouring of the jib- was it just steel bound wood? The rest isn't really a problem but, as the thing is to be attached to the layout I don't want to have to re-paint it once in situ.
All help gratefully recieved.
