I bought a new Futaba NA202MD12Aa from an ebay seller who has lots of them for cheap. Guess what - no data to be found - none that was real anyway, like I said, VFDs are great, just make sure of what you are buying and you will be happy. Elsewise you get some paperweights. Some of the forum users have made recommendations. I would venture to say those are safe choices. Try 'em.
For places where there is high ambiant light you can't beat them. I recant my statement of above RE: Noritaki makes . . of that I am not sure, but there are zillions of surplus vfd units out there that are non standard, and that was my point, not to badmouth noritaki.
