Here are two of the five buildings I've painted for the Manassas battlefield. The first is the Stone House at the intersection of the Warrenton Turnpike and Sudley Road. Today those roads are better known as Route 29 and 234.
The second building is the Robinson House. This is a great little model with a front porch assembly. I assembled the porch, painted the model and then attached the porch to the house.
Both of these castings are 10mm models from StarFort Models. I got them from Doug Kline at Battlefield Terrain Concepts.
I have also painted a model of the first Henry House, plus the Bryan Farm. The Bryan Farm is from Gettysburg but has been transported to Manassas in order to fill in as the Lewis House. I'll try to add photos of them some other time.
