SR 1930s colour light signals

[10800]

Does anyone have scaled drawings or dimensions for the colour light signals introduced with the Brighton line electrification in the 1930s? I have some photos but some definitive measurements (for 4mm scale models) would be very useful.

Thanks in advance.

Note that longer hoods were fitted to all (then-existing) SR colour-light signals as emergency ARP in the latter part of 1940, and these longer hoods then became the SR standard.
