This is a model of a large masonry building with metal roof, suitable for gaming any battle set in an urban environment during WWII. The model is one piece; the roof is not removeable. The model comes with two separate cast chimneys, which must be glued in place. The model has solid cast windows. This will be a GREAT addition to you 10mm WWII line...it is rare that you can find city buildings for Eastern Front gaming in 10mm scale!
