McKenzie & Holland supplied signals to many British railway companies, including the Highland, Great Northern, North Eastern, Great Eastern, North Staffordshire, Great Central, Furness, Taff Vale, Barry, Rhymney, Brecon & Merthyr, and Cambrian Railways. They were used on the Northern Counties Committee in Ireland, and in Australia, New Zealand and many other countries. Please note that this fret does not include any balance levers; suitable items are S001 (etched) and SC0041 (cast).
Modellers of the Great Central, Great Northern and North Eastern Railway are advised to purchase S003/2, S003/3 or S003/4 respectively instead as these contain arms for just one of these companies together with balance levers and are thus better value.
Adaptors for the easy construction of slotted posts are available (S007/1 and S007/2).
The actual size of the fret is 84½ x 54½mm; it is etched in 0.012″ brass.
