Evening Ken,
I'm just off home now, but thought I'd ask a couple of questions to narrow it down a bit more for a look when I get home later!
I take it were're looking up at it, inline with the extended flaps and it has upturned wingtips, truncating the starboard wing?
Those swept inboard leading edges remind me of the French Wassmer or maybe a CERVA, any point in pursuing this line of thinking??
WTF is that "pipe" sticking out of the wing root and that loop by the Fin L/E?? I see something on the far elevator tip, so is that another view of a similar loopy thing (it seems to be pointing the wrong way for a horn balance)?
