: Lever 6 controlled the auto signal E 291 and was required because the
: points from the car siding were situated in the normal speed overlap of
: the home signal No 8 provided crossover 7 was left normal. Crossover 5
: was apparently outside the overlap area and therefore even though it
: survives today the lever control of E 291 is not required.

5? Sorry I am lost here. (now I think of it I think you mean 15).
8 is the home signal, after that is a facing crossover 7 to the up
line, and then 11 from the car sidings (removed) and 15 which is
the reverse crossover from the up to down line.
So you needed to control the previous auto becuase of the trailing points
but not facing points? ie crossover 7.
So now when 8 is normal E291 will be at stop but has no control? Why?

: > 14,20,28 spare?

I think in theory 14 is spare so you could have both car sidings with 
their own signals. 20 and 28 would fit in as signals at either end of
the road between 1 and 2 (but since the middle road was removed they
were never needed)

: > 23? something to do with the crosslocked frame???

: 23 was the crosslock lever which when reversed, electrically released
: lever 1 in the ground frame.

What did the ground frame control?
as far as I can tell 1a was the release 2a was the points from no.1 road
3a was the catch from siding d and 4a was the points/catch from siding
E

What else did 23 lock when reversed ie main line points/signals.
