I'm assuming that it's the film that's thrown general knowledge off then as I recall the Warlord Games version is plastered

The film was made on an extremely low budget. The makers located an old farm with two buildings that would do as a set.
The location used and buildings looked nothing like its historical counterpart. Fifty years ago not many people cared about accuracy like they do today. As for the WG model, i don't think you'd really like my opinion, but it's a good gaming piece:-X
