Our house most likely is fabricated in a Southeast German factory. We like to go to that region because of it. But also the surrounding countries are in favour too. We see always a lot of houses looking like ours. We often find authentic parts that are very useful to us. In The Czech Republic we did find locks and hinges at a rubble yard, especially nice was that they where made with the same casting mould as ours.
Even at Sardinia we did find something and at a market place in Turkey we did find hinges we seldom see in The Netherlands, new and in big boxes. The hinges are used to let the window frames turn towards the inside of the house.
We often did try to find a similar house as ours. Still without any success.
