Ok. So, after some careful looking and studying, I've come to the conclusion that the 4 little bits I couldn't figure out are, in fact, un-used extras. They don't appear on the website/eBay parts photos (although apparently I didn't get a full complement of brass wires either... but I can work around that easily enough). The only one of the three kit versions to list the parts is the Daisy Cutter, but their location in the mould leads me to believe that there was no real point in trying to remove them.
With that settled, everything else now makes sense. So I glued a few more of the bits on, lest they become wayward snacks for the carpet monster, and I kept doing surgery on the cabin windows. So far (SO FAR) I've only snapped one bit of framing, but it was easily replaced with a bit of styrene and some CA glue. Still some more windows to drill out, so... fingers crossed!
