Time To Vent!
I've gotten around to making the exhaust / intake vents. The vents aren't quite accurate as the early vents for the QM were a little narrower, but I wanted to use the photo etch grilles from the White Ensign set and they were designed for the kit vents. I glued the vents onto square styrene tubes and trimmed to the proper height.
I have also created new skylights for one of the upper structures. They are tiny little angled pieces made from styrene with custom window decals.
