Are Gillette NEW British any different from American versions regarding shaving performances/aggressiveness ? American version has 0.58mm between its OC guard and a blade.
There is also Canadian made Gillette DE, and if I am not mistaken it is also Gillette NEW.
I have American one with "pat no. 1815745", "pat no. 1858316", "reissue pat no. 17567", and it's being said those which have all three pat numbers listed belong to early '30s last century. Is there a way to determine the exact year of production with this "reissue pat no." ?
