I have been trying to identify this cylinder that I found on a walk. What could it's purpose be?

It's imperative that the cylinder remains unharmed.

The green colour makes me think it's a halon fire extinguisher.

Please do not bully the cylinder.

Given the originally red colour, the slender shape and the mounting, it was probably a gas bottle for acetylene. The valve is missing. The text mentions "Duisburg", probably the location of the manufacturer.

EDIT: Acetylene bottles have thead for a protective cap. So my next guess is a fire extinguisher.

Acetylene and then you jump to fire extinguisher.

I hope I‘m not near you when you try to fight a fire.

We played with the contrast of the picture and we think the first "u" looks like it is actually an "M". 🤔

No, it's lower part is missing. Same for the B. The text says ~G?S DUISBURG. I can't decipher the name of the company completely ~~, probably RHEINGAS.~~

What sound does it make if you hit it with a stick?

What happens if you light it on fire?

[-] Knossos@lemmy.world 12 points 1 day ago

We rapped on the side and it felt very solid, we didn't think to whack it with a stick.

I would say that a sledgehammer would be the right tool here.

Green is usually for Argon or other inert gases.
