Maybe I'm just not seeing it, but I can't find the Aristocrat in the shavewiki page on production dates for Gillettes. Could somebody point me in the right direction? Also, I have one Aristocrat that's gold colored (very good condition, with case, no procution date) and one that's the same basic nickel plate color as other Gillettes (near-mint condtion, no case, Z1 production date). What's the difference between the two? And what are they worth? Thanks.
