The Australian War Memorial site has a page about the Douglas Boston

By December 1941, the Douglas Boston was becoming increasingly important in the desert war. The Martin Marland was vanishing through attrition and the Baltimore was not ready yet, so squadrons converted to the Boston, which was being produced in numbers. The Australian War Memorial has a page on the Boston and a picture of a SAAF Boston being armed. They typically bombed at low level and high speed during daylight hours.
