Huttons are a long established and very large scale producer, starting life in 1800 and its name is still trading today.
Much of their early success was due to the licence granted to them by Elkington and Co to use their recently invented electroplating process.
Huttons developed a new nickel alloy in the late 19th Century that was ideal for plating purposes. It was called British Plate and is identifiable on EP flatware by the "BP" mark. They are an example of a company who machine-made silver flatware in Sheffield and sent them to be hallmarked in London.
