Thanks everyone for your kind words and I liked that Photo.
Out of all the books and articles photo's etc that I have collected on the steel industry one of my favourites is the "South Buffalo Railway" by Stephan M. Koenig. The photos of the furnace's in the book are what I have tried to base my version on or what inspired me. A wonderful book.
My version of the pouring house will be slightly different to some of the other models around I choose to enclose most of the pouring floor (it will still be there but not easily seen) that way at my leisure I can finish the interior which is really a model in itself. I will try to get the walls together today and place it on the layout that way you will hopefully see what I am trying to accomplish......heavy industry in O scale. Thanks again. Roo.
