Identification please - is it even military?

[trendier1]

Hi, thanks for allowing me into your group of expertise! I just joined to ask you about the item in these photos. My brother has 2 of these, and he has asked me to try to get them identified. He bought them at Wimborne Market possibly 50 years ago, thinking they were shell cases. Now he’s not so sure because they are unmarked and because he now thinks they are made of copper(?). Length without base 25.5cms; with base 28cms; diameter 7cms. The basal nut looks like it has been struck. Do you have any idea what they could be please? Are they even military? Thanks for any help or guidance!

That was quick thanks, and it looks like that must be what it is! Much appreciated!!!

Yes, Fire Extinguisher.. I forget who made them, but they were an early form of dry powder extinguisher.. There was a pistol grip firing device that clipped on to the back. They were often found in commercial kitchens and were mounted on a board on the wall holding 4 cartridges and the firing trigger.. All painted red.

This is an earlier version of the device.

Just in the interest of accuracy of conclusion Bombdoc or anyone else, though now obviously off-subject for this ordnance group, can you find one of those pistol extinguisher canisters to be 70mm diameter which my item is, or of the same length including base? I can find one like you picture on a Bristol Museum site to be only 50mm diameter. They are also obviously red, with identifying markings, and made of steel. My item is copper or brass with not a trace of colour or marking.
Alternatively, in my hunt, the nearest I got before giving up was it might be the inner cylinder of a marine chemical foam fire extinguisher (see attached diagrams). My item’s cylinder being copper or brass would resist the outer and inner chemical solutions it is bathed in, and there is mention of holes in the end through which the chemicals could mix when required. Being an inner part it would not need identifying markings. Don’t I also remember another occurrence of one of these, was it on this group, being fished out of a harbour(!) in New Zealand?

I’ve now found this as another strong possibility, but with no accompanying images of what is being described to match my item against. Tantalisingly close but still inconclusive!
