Not Ranked
Hey Greg I'm talking about the spanner sizes. Yours says AF (across flats) they should read W (Whitworth) and BS (British Standard) the size on the spanner refers to the thread size of the fastener.

Note the bullet shaped imprint vs the rounded end rectangle. Also note the spanners are the same size jaw opening with the different sizing system numbers shown.
