Aren't they basically the '46 Aristocrat with different plating? Or do they shave differently? For that much, I'd rather buy a Brit Aristocrat IMHO.
The head had seen several changes by time the 50s had rolled around. The safety bar style and center bar are the most noticeable. Some guys say the 46-47 heads were more aggressive.
I always though the 46-47 was mild.
