Brandolini notwithstanding, the suggested history of this item is that it was found in 2017, and has spent time since then in a Fishermans home as a table, until it became known it was possibly from MH-370. Without going into the forensic analysis that is used to support it's provenance, it certainly is consistent with the left hand aft LNG door, which had the markings of the steering limit line, at the rear, and "MO" at the mid forward side of the full panel.
Is it consistent with the left aft nose wheel-well door though? Any concerns about the apparent lack of curvature of the item, the absence of any remnants of the red steering limit marker, the use of at least five separate pieces of honeycomb core material (including one "filler" piece that is only an inch or so wide), or the inconsistent quality/thickness of the bonds between the sheets of honeycomb core material?
