Well I don't think it is for smoke discharges as it is for about a 6" dia item. It is aluminium and it's fabricated. It is just above the floor level and it is not covered by any bulkhead panelling. It has those two threaded holes and I can't see anywhere for a strap to hold something down. It does not line up with anything on the engine and I cannot see where there is any wear marks
