I have for free a brand new, in box, 1kg powder fire extinguisher. This comes with a mounting bracket and so perfect for bolting in to your van. I purchased this for my T5 conversion about 18 months ago but in the end went with a slightly smaller one as this didn't fit where I needed it to. Collection only from Kidlington, Oxford (OX5).
Good question - have just looked and it says 5 years from year of manufacture which was 2017 - so 2022. Sadly this is older than I thought (bloody ebay!) and so am changing this to free if anyone wants to collect it. You can have first refusal @its ted
