I know that Australian troops used Jeep springs to make 'fake' swords with the sole intention of making money from understandably gullible G.I's newly arrived in the region, during, and after the end of hostilities with Japan. I have a picture somewhere, but wasn't able to find it just yet, but will post it when i come across it----promise.
However, i do have a some pictures i found of PETA from Indonesia, who went on after the war to fight another 4 yrs against the Dutch who were trying to retake their 'Colony' back after losing it to the Japanese. These Collaborators welcomed the Japanese and saw them as liberators from the chains of Colonialism.
Quoted from Wikipeadia:
"The Japanese military also provided Indonesian youth with military training and weapons, including the formation of a volunteer army called PETA (Pembela Tanah Air – Defenders of the Homeland). The Japanese military training for Indonesian youth originally was meant to rally the local's support for the collapsing power of Japanese Empire, but later it has become the significant resource for Republic of Indonesia during Indonesian National Revolution in 1945 to 1949, and also has leads to the formation of Indonesian National Armed Forces in 1945."
