ID Markings on Japanese Aircraft MG?

[Alan Smith]

Here are photos of the markings on a WWII Japanese aircraft machinegun (Type 97) that I recently purchased. I do not yet have possession of the gun, as I am waiting on the federal BATFE approval process to be completed.

I assume that the "97" portion of the markings refers to the model designation of the gun. Likewise, the "6579" portion of the markings is the gun's serial number (at least, that is the number that has been used in BATFE's records as the gun's serial number).

What I am really curious about is the "18" and related markings. Is "18" the year of production, i.e. 1943? What do the other symbols/markings mean?

I would be most grateful for any assistance in deciphering these markings.

Thanks!

Another view.

Again, I very much appreciate the expertise in the Japanese language and military weapons markings that exists here on the Forum, so I am hopeful that some of you can help me understand the markings in question.

That is pretty sweet!

marking is "shi-18-yo" but I couldn't tell you the meaning, aside from possibly what you have stated above, that being the date of 1943. Usually the Japanese marked the heck out of their firearms. I wonder if there are further markings somewhere else on your machine-gun?


I wonder if the 77 is the caliber for 7.7mm.
