scalescenes.com factory kit and I've had all the parts printed out for a week or two. The problem was the windows.
The kit includes a sheet of window frames that you are supposed to print onto transparent plastic or tissue paper. The problem is that being such a prominent structure on the layout I thought I needed something a bit more than this. Fortunately Brassmasters do a range of etched brass windows which are specifically designed to fit scalescenes.com kits, so I ordered enough for the factory and the small station in case I added that to the layout. Well my order arrived yesterday -- a very satisfying ounce of etched brass (and I really do mean an ounce as I used the kitchen scales to weigh them).
Most of the windows are in two parts allowing you to model open windows, should you so wish (I won't be), so I now need to assemble, prime and paint all that brass, but at least I'm now one step closer to being able to construct a dark satanic mill.
