I am trying to replace one of the two circular cast iron coal hole covers which cover the coal delivery holes into the cellar of my london house. Does anyone know where I can get one of these? Many thanks.
Have a look on Salvoweb for a salvage yard close to you.
A local foundry could take a mould of yours or a neighbour's a cast a new one, might cost a few quid though. Alternatively any metal basher will cutt you a new one from a blank but it won't look like much.
