Made some more progress on the background machine shop/view block building.
I've had these structures for close to forty years (!), they are not "kits" but one piece castings. Had to chop them up to create a new form to fit the layout space. The windows and skylights are way oversize, so I tried to de-emphasize/decontrast them with dark colors. The windows are okay, the skylights, not so much. Tbc....
