Your unidentified green Pilot is a 78G. From my understanding, they were recently discontinued.
It is indeed a 78G, which I learned from a ten second google search. Which teaches me to always do my research before I post 🙄. I got the same sense that they were discontinued, I think because they were basically replaced by the Metropolitan even though they were both being made for several years. Either that or the 78G is only sold overseas, it might be a combination of both. Either way I’m very glad I got it, I love dark green/gold pens and it’s a combo the Metropolitan isn’t offered in.
