Well....I've completed my N scale Walther powerplant with some minor bashing. This is the standard Northern Power & Light kit with these additions: 1.) One-story side addition -- the piece sticking out of the side is half of the Model Power army munitions depot. 2.) Side wall vent (grey squares) 3.) Two roof smoke stacks. 4.) Large machinery added to roof -- not sure what this is but a plant near me has one 5.) Custom signage 6.) Window glazing made from quilter's patern plastic -- with panes removed 7.) Full interior -- you can't see the interior unless it's lit, so you'll have to wait for that...but I posted some previews on a previous thread. I think the only other thing I may do to it is add some rust streaks coming down from the roof vents.
