Here is one in use by the Royal Netherlands Marine Corps (RNMC) at Soerabaja, Java, Netherlands East-Indies/Indonesia. December 1946. The mobile hospital of their medical company (MED CIE) had two of these armoured abulances.
The RNMC was trained in the USA and they used US equipment throughout. As the Netherlands East-indies Army KNIL had received a batch of these Scout Cars before WW2 broke out in the Pacific, these ambulances
may have been converted from re-captured vehicles.
