I either totally forgot about or didn't realize until reading the thread about the "early" #71 issue. Went and looked at the MPC #71 box sitting on the shelf here, and whaddya know... it's the early issue with the door scoops.
That's one I hadn't intended to build anyway, but certainly won't do so now.
