Rare 40s Workwear jacket

Not sure where to start with this one, but probably one of the best faded jackets I had, from my personal archive.
Found in the jungle sourcing 2-3 years ago outside Ho Chi minh.

Labeled as 1949 from Vietnam Hanoi.
Cannot confirm this but the tag is correct to the Era.

Incredibly conditioned for its age, everything is very functional and no big rips.

Sold two others recently (bigger sizes) to a collector in Japan for 1800$ and this is better than that.
