Cooker hood (Presteigne LD8)

Grey cooker hood - described an an Integrated Extractor in the information leaflet that came with it. Not sure what make it is, as there's no clue on it. In good condition and was working when we removed it when we redesigned our kitchen. It's been in a dry shed for about 10 years, so there's no reason why it wouldn't still be working, but we can't test it
