The "Modellbau-Werkstatt Bertram Heyn e.K." was founded in 1983. It began with architectural models: competition-, work- and presentation models.
Measuring displays, museum and functional models were soon added.
Since 2001, the "Modellbau-Werkstatt Bertram Heyn e.K." has been developing a track system for the gauge G. This was the starting shot for the whole railway program as it currently is in the shop.
Since 2015 we are a recognized training company for the technical model builder.
