H+C clock, 159-173 St John Street, Clerkenwell, Borough of Islington, London EC1, 2007 • And another 1950s-style Clerkenwell clock, advertising lift manufacturers Hammond & Champness, who inhabited this building until at least the 1980s. The clock is still there, as is a vintage H&C lift inside – there’s a great urban exploration video of it here (thanks to @casasecurityuk for the tip).
