so this aristocrat http://cgi.ebay.com/Gillette-Gold-A...817?pt=LH_DefaultDomain_0&hash=item3f034cb6c1 has the knurling at the top and bottom of the handle like the 48-50s aristocrats, but is not notched like the 46-47 models. the case is for a 46-47. is it 46-47 or a 48-50. i'm guessing a 46-47 because the notches were introduced in 48 when gillette introduced the cream dispenser to pull the blade out over the notches.
