I've just received from Italy 200 Super Silvers made in isleworth London.They are B2 so 2nd quarter of 1981. These shave really well for a 40 year old blade.
1st tuck I opened from one of the packs has blade code B4. So 4th quarter 1981.
2nd pack have the code C1 so does that make them 1st quarter 1982 ?
