I was out antiquing today and saw a British Aristocrat that I wasn't sure about. The pat number was 400, 621. The razor looked like it was actual silver because there was a significant amount of tarnish on it. It definitely wasn't dirty nickel or rhodium, but actual tarnish, which really made me think that it was made out of silver. Does anybody know anything about silver plated British Aristocrats with the patent number above? I could potentially go back and get it, but I thought the price was too high. It came in a large leather suitcase like toiletry kit. The razor case itself was silver in color with a purple lining, but as there wasn't any tarnishing, I don't think it was silver as well.
