I commented on the now-defunct site on unusual naming of British wrench brands. Here is another, "Spearpoint", that appears to hark back to British cultural memories of ancient charioteers under Cassivellaunus hurling spears at invading Roman legions. British members, please advise publicly on the accuracy of this assertion.
To meet the universal need-to-know requirement, this wrench is 4 3/4" long. The openings are sized front (back) as follows: 5/16 W (3/8 BSF) and 1/4 W (5/16 BSF).
