I developed the modelviewers to present railway models in full view. They are soldered from brass profiles and are custom made to order. They can vary in length or gauge. All depicted modelviewers are made to display gauge 1 models / 1:32 scale. Most of them are illuminated by neon light or powerful white light LEDs. The tracks can carry current, externally fed by sub-miniature connectors to enable certain functions of your models, such as lighting, sound, etc. The Mk.IV.2 version turns manually in a circle.
