Hello rickdeckard,
Welcome to the Ethnographic Forum. You are on the right track regarding your machete. This form, and a number of similar examples, have been referred to as Chindit machetes. The Chindit were a significant special forces group under M-General Orde Wingate who conducted operations in Burma during WWII. They were based out of India and many of these machetes were made in India.
You can read more about them and find further pictures in Ron Flook's book "British and Commonwealth Military Knives," (1999).
You can find more information here if you do a search for "Chindit."
I hope you enjoy your time browsing the Archives here and that you will post more items for discussion.
Regards, Ian
PS Here is
one thread from the past that might be helpful. Also. the pictures from the Flook reference.
