A couple of guesses that I couldn't validate.
My first thought was some sort of Japanese industry standards group that
might have pre-dated the present JIS (Japan Industrial Standards) but I
couldn't find anything along those lines. Next, I noticed the 6 digit
number which I thought might be a Japanese patent number. But I don't
know anything about the post-war patent system or if the number is in
the reasonable range for the period. The number could also be a part
number but I don't know anything about Nikon part numbers.
Now I'm out of guesses.
