Engine-cowl fragment — Mossel Bay

An engine-cowl fragment arriving on a South African beach is part of the western-Indian-Ocean field. Independent commentators (including Wise) have noted that engine-related pieces can be awkward for simple drift from some 7th-arc latitudes because of buoyancy and timing. Classification is not as hard as the serial-confirmed flaps. File it in the swarm, not as a unique identifier.
