Ultra rare Dual-Chinese character VFD tubes.

[Zac Huang]

As far as I know, these VFD tubes were installed in some refueling machines around Shanghai in the 1980s, and the number is probably no more than 1,000. In China, refueling machines have mandatory scrapping dates, making these tubes Ultra rare.

They are all 风光 brand, YS27-F, manufactured in January 1985. "加油" means "refuel" , "打印" means "print" , "开关" means "switch" and "公升" means "liter" .
