The kit represents the type of signal used by the Great Western Railway for new installations and renewals from the late 1880s until the advent of tubular steel posts in 1930. Many were still in existence in BR days, but the type is probably now extinct on Network Rail. Some still exist on the various preserved lines.

The kit may be built with either a 4' home or distant arm, or the 3' goods line arm. The goods line ring and shunting arm symbols are included.

Containing a real wooden post, the kit is designed for soldered and glued construction. Some simple marking out, cutting and shaping of parts is required. To see exactly what is involved in constructing this kit, download the instruction sheet as an Adobe Acrobat® file (129kb).
