Old or empty fire extinguisher (Rugeley WS15)

I'm looking for a 1Kg or 2Kg dry powder or CO2 extinguisher, preferably empty or past its safe-usage date. I'm making a tubeless tyre inflator and will fit a Presta valve so it can be pressurised with a track pump. I can always buy a new extinguisher and empty it, but that seems wasteful to me. Can anyone help please?
Can you help with this request?
