Vintage Britool model number AH687 – 11/16″ AF – 3/8″ drive single hex socket. Proper old school quality British made tools. Listing these as new old stock been stored for years with other items so will have the odd marks here and there and a little bit of rust inside. Please take the time to study the pictures carefully for condition and sizes as they form part of the description.
