So I'm trying to get her to join as either smurfette or Asrael or Azriel (Azrael was taken), cause she's really digging the research she's doing and the help you guys are providing.
She found some serial numbers (in the pic), but she says the markings aren't really lining up with the pages you guys have linked, and are difficult to read. She would like some help deciphering the first few markings of the serial number. I also have been corrected, the length is actually 20" (not sure if that's overall or blade, it has to be overall, I'm not always 6" off in my estimates

). (EDIT: I see the yard stick now, but it's kinda far away)
She thanks you guys by the way, and is a little awed by the collective knowledge here. (And she was wondering why the military parts of
Furious 7 was pissing me off LOL) I'm really digging the fact it's an IJN blade. I was 90% expecting US issue, or perhaps German.
I'm curious as to the notion that it's history could be traced using the serial number, would that be possible?
So, if any of these show some clues, she would really like the help:
She said there's a very faint Japanese pictogram just below the serial numbers that she never noticed before, but it doesn't quite show in the photo. (Side note, I'll look into doing some infra-red photo's to see if anything else shows up).
EDIT: Could we please leave this in GT for a bit, then move it over to the appropriate forum when we finish the research? I'd like to get a bit of extra traffic to the thread. Thanks!
