l James MacNaughton set up business in Edinburgh in 1864 and won acclaim for the 'Lock Fast Breechloader' and the 'Edinburgh Patent Hammerless Ejector', patented in 1879. This trigger plate action shotgun was similar to that of John Dickson's. Both companies went to court to claim design rights for the 'Round Action'.
