I bought the Old Glory 2 wheeled ambulance. Its a nice cart but not really representative of a 2 wheeled Coolidge pattern ambulance (original image below). So I broke out some balsa, tissue paper, and paints and added a 'canvas' top and frame. I also made a rider up with a hospital flag. Would you have seen this in the field? No... but I like all of my units to have colors for display purposes. I left him unglued so I can remove him during games.
