Found this, help me identify it(anti spark)

Hello, so due to a new family member I started selling of things I don’t have time or use for. My esk8 hobby first to suffer. Went through my boxes and found this…

Which anti-spark is it? Need help identify so I know what I’m selling :joy: tries searching but no success!

looks like volokno, now a defunct co. due to putin war.


Thanks for reply,

Tried searching and found some pictures of their anti-spark, maybe they had more than one model for anti-spark but this looks way bulkier in size and other components compared to theirs.
