Stephen Crookes was kind enough to share photos of his Belling Bomb Snuffer. I'd not seen an actual example before. Using a long pole the device was to be placed over a burning incendiary bomb. Appears from the advert that the bomb snuffer also contained dry sand that smothers the incendiary device (the top of the container had flammable divider that once burned through would allow the sand to fall). I'm guessing it would prevent showers of burning metal but if the device was on a wooden floor I would assume it would continue to burn through that though.
In passing, I'm also slightly concerned with another Belling 'war-time necessity' mentioned on the advert - a "Baby Cooker"...
