Thank you to Lyric1 for finding me the info for this skin.
"My Favourite" was a B-25C flown by the Royal Australian Air Force's 2 Squadron. It featured a field-applied all over camouflage of RAAF Foliage Green. 2 Squadron were based mostly in Australia for the whole of the Pacific war and flew reconnaissance and bombing missions against the Japanese based to the north of the country. In late 1941 the squadron were flying obsolete Avro Ansons but later received Bristol Beauforts, before switching to Mitchells in mid 1944.
