I’m a bit late with this news, as it was on the 1st December last year that the Whitechapel Bell Foundry announced it was for sale, saying,
Whitechapel Bell Foundry Ltd announces, with regret, that by May 2017 it will cease its activities at the Whitechapel Road site that it has occupied since its move there in 1738.
The Whitechapel Bell Foundry is the oldest manufacturing company in the country, having been founded in 1570. The current owners are retiring and are selling up. Spitalfields Life has an interview with owner Alan Hughes, who talks about unusually long lead times between an order for a church bell and its delivery. It also has an extensive series of images on the bell foundry.
