Headstamp ID CHNA

I only have the headstamp and not the case. I don;t collect above 20mm so this is an unknown to me. Told it is a 25mm cartridge. Does anyone have any info on this one?
chna 1953 9 1-1 25mm

Some kind of flare case?

Not a real cartridge case; this is a bullet lighter headstamp.



Thanks Fede.!
