Etched brass kit for two standard Southern Railway ground signals, as also used by the Somerset & Dorset Joint Railway and the Southern Region of British Railways. The signals may be constructed in either the early miniature arm form, or the later half-disc type seen in the photo. Some of the latter are still in use today.
The model is intended primarily as a cosmetic addition to the layout, but with care, can be made to work.
The actual size of the fret is 30½ x 22mm; it is etched in 0.012″ brass.
