Australia/Dutch

The Dutch purchased OS2U-3s and had only unpacked a few in the Dutch East Indies before the Japanese attacked, what survived the Japanese attacks were sent to Australia

Note the difference in the markings on the Australian OS2U above and in this photo. The center in the roundel in the photo was a red ball which was removed when friendly fire opened up on an Australian aircraft thinking it was Japanese, so it was deleted thereafter. After the war the space was filled with a red kangaroo.
