Interesting connection with Hythe in that is also where the Military rifle training ranges were in the 19th. and early 20th. Century. Maybe your Instructor stayed on in that area and set up as a Gunsmith. No doubt (as above) he sourced the gun from the Gun Trade and sold it on with his name. That was, and still is, common practice making English gun research a real head scratcher at times. Lagopus.....
