Excellent, thanks for that Stuart, in other words then, as far as modelling is concerned, I can treat it as a usual signal. I meant to add, how would things be different if there was a trailing crossover on the Colwich lines just at the right hand end of the platforms?
As for 39, no idea, but I can't seem to make it out on my britain from above picture which was taken in 1929, so perhaps a knotty oddity that the LMS soon dispensed with? They changed the rest of the signalling at some point between 1929 and 1950, which looks like it entailed replacing all the posts with LMS ones dispensing with the lower co-repeater signals.
Edit - just had a quick flick through one of my reference books, which talks about backing signals, consisted of a cutout B. This was 3ft 4in high and 2ft wide. It was mounted on a post with the lamp on top, which revolved through 90 degrees, in a similar way to the ground discs. All NSR signalling was Mckenzie and Holland by the way.
