Hi, folks
I have 5 pc. BEDFORD CHRO-VAN HEXAGON (12 ) sockets .
Sockets are marked A/F sizes 11/32 , 3/8 , 9/16 , 5/8 and 11/16 .
They are all stamped/engraved BEDFORD CHRO-VAN MADE IN ENGLAND and SHA with numbers according to size.
SHA 11,12,18,20 and 22 also ascending numbers of 34,38,56,62 and 69 .
Please, can someone clarify for me what those SHA numbers are ?
thanks
bst rg Kai
