Bike Rack for Three Bikes: Option to attach to wall or floor (Chingford E4)

Bike rack which fits up to three adult bikes (by putting a wheel into the rack). It can be screwed to the floor (we didn't find this necessary) or mounted onto a wall; sorry we no longer have the screws. See https://www.amazon.co.uk/dp/B01DKWQQFW for other photos. There is some rust (see photo), but it's still usable.
