In this extract from the TV series Filty cities, the ever game Dan Snow is shown the tanning process first hand by Andrew Par, owner of Britain's last working traditional tannery, J. & F.J. Baker & Co Ltd in Colyton Devon. (The Colyton tannery normally uses oak bark, which is a little less noisome.)
