As you are no doubt aware, Battlefront have been releasing some new buildings for Flames of War.
As I already have the 15mm Total Battle Miniatures ruins in my collection I was intrigued to see how they compared to the new French buildings from Battlefront for Flames of War. One thing I have found is that when a manufacturer says 15mm this may not always be the same 15mm that another company uses.
Here are a series of photographs of the Calais House next to various 15mm ruins from Total Battle Miniatures.
As you can see they do fit in quite well.
Here is the Calais House compared to the ruins from the Jagdpanther boxed set.
Time to get painting the ruins methinks.
