To my eyes the cone in #146 is a trailing edge cone with a piece of black strapping around it, presumably from the salvage effort. You can see a short length of it continuing on the plastic sheet upon which the items have been laid. And the semi-cone in #149 looks to be from the leading edge of a flap fairing. I'd not jump into second-aircraft theories on the basis of these photos, at any rate.
