That's been on before, I think. What's worth remembering here is that Greco is essentially a Japanese home market brand, so production of these & other copies continued long after export stopped. The serial number on this one (B000914) seems to suggest February 2000, and the condition (as far as one can see) and modern hardware support this, imo. With later Grecos, production wasn't solely in Japan, and this one doesn't state a country, at least not on the neckplate.
The price would be pretty much right for a 70s example in average/good condition, but I'm not sure what a modern one like this would go for on Ishibashi or if Kukkunyan was selling it on here.
