I have obtained a number of Pola building in need of major repair ( a tree branch fell on the out door community and squirrels ate the drain pipeson the buildings).
These building are still worth rebuilding if parts are still available, I just have not found a source. I need a roof piece ( metal sheets), a smoke stack, and gutters and drain pipes. I’m not even sure where to get scratch build parts to replace these. ( small rural station house)
