I'm creating a fairly large 1950's town scene ( 60 sq ft.) on my O Scale railroad. In talking with a professional fire fighter friend about spacing the fire hydrants he asked about the town's water supply. After further discussion we agreed a tower on the edge of town would add interest to the scene. With a long list of higher priority projects, I'm not looking to scratch build a water tower. What commercial towers do you recommend I check out - photos would be appreciated.
