I first became aware of these breech - loading flintlocks after reading the excellent Dewey Lambdin books on the British fictional naval officer Alan Lewrey. An American writer whose knowledge of the British 'Nelson's Navy' was encyclopedic! Firstly: does anyone here have one of these and how effective are they? Secondly... is this off topic on a muzzleloading forum?! I would like to know if anyone today makes a replica, but I haent seen any on web searches.
