From what I can gather they're NJS stamped Dura Ace FC-GA200, but hard to find any information on NJS stamped variant. Any info would be appreciated, also a rough estimate on their worth. I'm based in New Zealand so parts like this don't come by often (or ever)

Pretty sure it uses iso taper instead of jis on the non njs version. There’s basically no info online because this existed in a niche market (japan in the mid 70s) and without anyone uploading documentation online there’s no way to know the full specs, but it’s safe to assume it’s from the mid to late 70s.
