This pack contains etched parts to construct a Stevens & Co. 2-doll wooden post bracket, as used by the London & South Western and Lynton & Barnstaple Railway companies. The design was introduced in the 1890s, and was used for new contracts until the introduction of the lattice post design (S0016).
The brackets are 12mm (3′) wide x 16mm (4′) deep; the trimmers are 40mm (10′) wide x 4mm (1′) deep.
The parts are etched in 0.015″ brass.
To model a complete signal as shown in the drawing, you will need: a base post (S0017); two dolls (S0033 series); signal arms (S0011 lower quadrant or S0012 series upper quadrant); finials (SC0028); lamps (SC001 lower quadrant or SC006 upper quadrant); and ladders (S009 series).
