Hi all. I'm not much of a poster, but I thought this might be of interest to the collectors concerning Gillette Aristocrats. I had always thought that the 1946/47 version had a smooth upper band and the no-notch center bar, and that the 1948-50 version had a knurled upper band with a notched center bar (pic #1), but, here (pic #2) shows an Aristocrat with no notch on the center bar but with knurling on the upper band. Strange, yes?
