Cooker Hood (W7, Grosvenor Road)

Metal design, maybe stainless steel? The buttons don't work properly, when you press them they won't stay pressed. Currently using sticks (as on the picture) to convince them to stay pressed.
The extraction pipe enters on the right hand side and the decorative chimney has a little cut over there and also the decorative plastic cap (like the one visible on the picture on the left hand side) is missing.
Needs a clean.
Otherwise operational.
