I have seen quite a few of the alu-minium .410s, and they all had the 'WCC 52' headstamp. They were, indeed, loaded for aircrew survival guns. As for the nickel plated shells, I had one that was a bit less than nice, and tried the vinegar approach. It gave typical results as far as the inside crud was concerned, with no effect on the plating. That was my experiment! I cannot guarantee results with your nickeled cases.
