There are some wonderful gunmakers lurking under the radar, as it were. One of my particular favorites is the firm of John Harper. There were three Harpers, Grand Father, Father and Son. All were immensely respected Birmingham gunmakers, respected not only by their Black Country peers, but also most tellingly by the best London makers.
In fact, Harpers made up many of the Robertson named Boss boxlock ejectors, the majority of Frederick Beesley's boxlocks, as well as those sold by Wilkes, Churchill, Woodwood and Pape.
