I have a book with a few lines on the Maryland and this picture, I can only scan it upside down? and it has degraded a bit electronically turning it the correct way up
If you want a full quality scan drop me a PM that an e-mail address. It does look like plain flaps and that part of the engine nacelle dropped down with them.
Looking at the picture on the thread it does not look that bad, a useful shadow across it picks out some of the lumps and bumps!
