Sadly, they're not in any scale I'm looking to play - they might work for 6mm. There are even really tiny cars all over the place. There were about 12 of these boards, and I harvested as much as I could at the job site, and took two home to try to salvage more buildings that could be converted for use in larger scales.
Below, a big bag of trees that might become hedges or shrubs for 18 or 20mm games. Waste not, want not!
