I have begun Betexa's Pernstein Castle, published in 2003. The scale is 1:300.
The construction procedures for this Czech model are completely different from German and French designs which are platform built. The parts on this model do not extend down to the base. A rising part such as a ramp, rises and literally 'hangs' in the air, to be attached to other parts which are also suspended. The parts depend on each other to hold their position and shape. This will be modified. The parts will have added card pieces that will carry on down to the base.
These photos show the entrance ramp, bridge and gatehouse to this large model.
