Established in 1965 when two smaller family firms united, they were originally based in Shelton Street in London, and was apparently the first UK company to import Guitars from Japan. In 1974 it moved to Tonbridge, and again in 2001 to Crowborough; the firm closed in 2012. 

At the time of them being in London they had a brand of Guitars and other Chordophones including a Japanese made 5 hook banjolele, branded Sheltone, (probably from the street name? I have also seen it said the this brand was distributed by A.L.Schitnasty and Co but if you actually pronounce the name you may think, like me, that this is a joke nome de plume - plus I have seen Sheltone Guitars with labels saying they were made for Fletcher, Coppock and Newman). 

Over the years they have distributed a number of other brands including Lorenzo and Sierra, not the same as the US Sierra, Guitars and Ukuleles plus other brands of Guitar, Drums, Keyboards and other musical equipment. I have heard they had some instrument they branded Kent but I have no firm evidence of this and one of the sources just said percussion, (and the was a US drum maker called E. W. Kent), and having seen nothing it could be they were distributing in Europe for Buegeleisen & Jacobson? 

J.T.Coppock ltd., one of the firms that united to make FCN use to brand firstly Egmond and then Japanese made instruments, including Ukuleles, as Antoria.
