I went to a local garage sale today and bought a box full of tools for 5 bucks . In the mix of sockets and old spanners was a D/I\D marked open spanner branded ZIRCALLOY . This is my second ZIRCALLOY spanner with the DD markings .
Were these spanners issued with vehicles as sets in a canvas roll ? The spanners are SAE sizes .

BTW I found in a box at the sale, a Morris Commercial radiator cap
in as new condition .
