Mckenzie are builders of interlocking frames and brass HO scale signals.
Our interlocking frames are available in 3 flavours;
Mckenzie Style (A Pattern - Victorian) and a NSW Style that can also be used for some British Railways
We also build ground frames, these are a smaller frame in size and are for use where 1 or 2 points are controlled.
**please note that these smaller frames are limited in the number of levers **
Victorian somersault semaphore signals and colour lights.
as well as NSW lower quadrant semaphore signals can be built to order.
