Thes 3 photos show a 4mm scale GWR tubular bracket signal under construction.

Methods are pretty much as case study 1, but here no working lights or servo motors were required.

First photo shows main structure in primer, second - complete except for operating wires.

The signal is based on the 1943 branch home bracket signal,

which was installed at that time because of the revised track layout.

The bracket had to be modified to suit the prototype post (doll) layout, which differs from case study 1.

I’ve gone into greater detail on the construction methods on RMweb

I have also built the (Branch/up) Starter signal which was at Brent.

This was a square post bracket signal and can also be seen on "A nod to Brent".
