BG Studio Scale Triangle Ship

[JAWS]

I think that piece sitting on the turret is updside down.
Lee you should scratch it.
You probably already have the kits.

That makes even more difficult to figure out...
The piece underneath looks like a wheel with tyre.
I'm wondering if its aircraft which may be what the piece on top is from.

Well did a little yesterday adding the styrene to the side canopy walls.

Pictures later.
