There was of course certain Japanese presence in SE Asia. I recall years ago finding examples of Japanese katana among swords of India. It seems in many discussions, there have been mentions of Japanese throughout these regions.

I don't see any resemblance to a matchlock of any sort. This is a percussion-lock gun, the two mechanical systems don't have anything in common. The Japanese also didn't make side-by-side double-barrelled matchlocks (although they did make revolving three-barreled matchlock carbines, the manually-rotated barrel system resembling similar ones made in India.)

Chronologically, the 19th cent. heyday of percussion muzzle-loading guns is much later than the Japanese presence in SE Asia that you allude to.
