I finally found someone who will pour me this house. I myself have not been able to pour as my foundry equipment does not allow for such a large cast. Now comes the forming of the first house and the selection of the optimum, the price / quality ratio, the material for molding. With the price we determine when we choose the resin.
Perhaps the price is not too small, since the house consist of many parts. A trial batch is a set of ten. A further will depend on demand. These homes are suitable for the games in 28 mm, dioramas 1 / 48 for modellers of military vehicles. And cover a large time period from the end of XIX century until our days. I think the demand for these kits will be, so this trend will continue.
