I am not sure but two things but opposite screams wing window latches, door handles or something of that nature. Obviously door handles is wrong as he said so and unless I'm missing something an inch thick chunk wouldn't be enough to fab outer door handles. ALso that chunk appears to be in the 8x8 or 10x10 area so that much material for wing window latches would be overkill.... unless he is finally starting to fab multiples for you guys.
