Stevens & Co. supplied lattice dolls to many pre-grouping companies, most notably the LSWR, LC&DR, H&BR and all Scottish railways except the Highland. The SR also used them on both the lattice and rail-built styles of bracket. They were also found in lesser numbers on the NER, LNWR, SECR, LYR, and the CLC.
This pack contains two dolls only. For a complete signal, you will need: an arm (S011 lower quadrant or S012 series upper quadrant); a finial (SC02/13/17); a lamp (SC01/6/11/25); possibly a ladder (S09 series); and a suitable base post and bracket.
